PREFACE
Unmanned Air Vehicles, which include RPVs and autonomous platforms have had a long history in the military field.Recent advances in guidance and control, in sensors and In data processing have led to an upsurge of interest in such systemswithin NATO. Several new RPVs are under development and there are numerous lessons that are being learned during thedevelopment and deployment of these systems.
This symposium intended to examine the state-of-the-art in the unmanned vehicle field covering both short rangesystems for tactical reconnaissance, target spotting and fire control and the long range systems carrying out surveillance tasksand autonomous platforms.

TECHNICAL EVALUATION REPORT on the
47TH GUIDANCE AND CONTROL PANEL TECHNICAL MEETING
Symposium on
GUIDANCE AND CONTROL OF UNMANNED AIR VEHICLES
I. INTRODUCTION
The 47th Guidance and Control Symposium on Guidance and Control of Unmanned Air
Vehicles was held at the Letterman Institute of Research, Presidio of San Franslsco,
San Fransisco, California, USA, from 4 to 7 October 1988. The Program Co-Chalrmen
for this meeting were Professor John T. Shepherd of the United Kingdom and Dr. John
Niemela of the United States. The program, as presented at the symposium, is
appended to this report. The complete compilation of papers will be published as
AGARD Conference Proceedings.
Unmanned air vehicles, which include RPVs and autonomous platforms ha-e a long
history in the military field, characterized by long periods of neglect and
indifference and short periods of intense interest. The motivation for addressing
the guidance and control of unmanned aircraft at this time sprang mainly from two
significant trends. First, the ever-increasing lethality and accuracy of modern
weaponry is monotonically increasing the risk of carrying out manned missions on the
battlefield. Thus there seems to be an expanding need for unmanned air veK:-les to
carry out an increasing diversity of missions, both offensive and defensive. Second.
using the same technologies that are producing this increased battlefield lethality
together with emerging concepts of artificial intelligence appears to offer the
potential for unmanned systems with significantly enhanced capabilities.
Consideration of these two emerging trends led the Guidance and Control Panel to the
conclusion that now was a propitipous time to explore the situation through the
vehicle of a symposium on the subject.
Accordingly, a symposium was organized on the subject of guidance and control of
unmarned air vehicles with the stated objective of examining the state-of-the-art in
the unmanned air vehicle field, covering both short range systems for tactical
reconnaissance, target spotting, and fire control, and the long range systems
carrying out surveillince tasks and autonomous platforms such as c-ulse missiles.
Although the title ot the symposium was limited to the guidance and control of
unmanned vehicles, the scope of the symposium was in fact much broader. One session,
for example, was planned to cover operational concepts, that i7, if, and if so how,
an unmanned system should be deployed in lieu of a manned system. Other sessions
were planned to cover the design of the total unmanned vehicle system, optical sensor
systems for unmanned vehicles, systems external to the vehicle needed for a total
capability, and the evaluation and test of complete unmanned vehicle systems in
addition to the core subject of guidance and control. The level of success achieved
in developing meaningful discussion of these topics was uneven, as will be discussed
in the body of this report.
This evaluation report includes consideration of the comments and
recommendations which were received from the participants in the symposium on the
form appended. Such comments are a great help to the evaluator and the efforts o4
those who took the time to make them are greatly appreciated.
2. DISCUSSION
2.1 Keynote Address
The keynote address was given by Rear Admiral William C. Rowes, Director of the
Unmanned Aerial Vehicles Joint Project in the US Department of Defense. This project
has only been in existence for a short time so that only planning activities have
taken place to date. The most significant point is that the US DOD is taking a
corporate approach to the exploitation of unmanned vehicle technology after years of
false starts and inter-service rivalry. A broad spectrum of missions is being
addressed including reconnaisance and surveillance, target acquisition, command and
control, meteorological data collection, NBD detection, and disruption and deceptinn
missions. (One point brought out by Admiral Bowes with which this author strongly
agrees is that many more uses for unmanned vehicle systems will suggest themselves to
operational system users as they get their hands on the systems. If is unrealistic
to expect that all possible system appIcations can be accurately assessed. or indeed
even thought of, by rear echelon systems analysts.) Consideration of the r.eed for
systems to carry out these missions led to characterization of four types of systems.
These are: close range (0-30 fi), short range (150 km. 300 km desired), medium range
(700 km), and endurance which is not characterized by range but rather by time o+
flight which for this system may be as long as 36 hours. A.dmiral Sowes ished his
address by challenging the technical community to develop produce and support -iale
unmanned vehicle systems and assuring the community of the support of his office in
using such systems.
2. Sesson . Goerational Concepts
The first paper of this session, oresented C, Dr. Mimer of 05APU. was a summaryof findings from several AGARD Aerospace Applications itudies on unmanned aircraftaoplccations. The studies addressed the use of unmanned aircraft in the groundattack, beyond visual range alr-to-air, and high altitude long endurance surveillanceand target acquisition roles. Dr. Rumer s presentation was extremely comprehensive.He explained how AGARD studies are commissioned and accomplished as well asorese-ting the results of the soecixic studies being addressed. Point designs kot
vehicle, launch and recovery modes, command and control methodolOgies. on-boardsensor requirements etc. were presented 'or each mission conside-ed.
the other paoer in the session, presented dv Mr. uansforo of British Aerosoace,was a r-oort of studies done by his firm on the efficacy of unmanned fighteraircraft. (Mr Hansford s written Caber is unfortunately not available, as of thlwriting. In addition, due to techrccal oi
tficuities. his visual aids were not shown
urtil his oresentation was almost over. Ths makes assessment difficult. I willsa1 . however. that his oresentation under the lircumStances cas heroic.I
:he conclusion ox both oapers was that proberi designed unmanned airrrafts,stems for certain missions are feasiole. CJe interesting point brought out by Mr.Hansford was that unmanned systems should have a life-cycle cost advantage overmacined sy-tems because machines don t have to p-actice.
Session II: Renuirements and Sysems

That is: What mission is an unmanned aircraft suiteo for and, havingdetermined that. how should the unmaned system be implemented. The Cader. Pesentedov ii.

trd.
The next paperpresented by S. Sbuelz of Meteor, was a straightforward
description of the autopilot o the Mirach 100 air-vehicle. The concept is somewhat
unusual in that it uses OMEGA inputs in a differential mode for navigation.
The nent paper, presented by M. Redoutey of Thomson-CSF, was a description of
navigating RPV s using a radio-location system with a number of ground stations and a
beacon on the RPV. It was stated that the system designers rely on short pulses,
power management, and random-like times of transmission to avoid detection and hence
jamming. It would seem that these ground transmitters could be one of those C3 nodes
sought in paper 21.
the next paper, presented by H. Zinner of MBB, dealt witn navigation by
processing images from passive sensors. The authors frankly stated that this
approach is presently not feasible but may be in the future. If made feasible from
the computational point o view, the advantages of total passivity with connectivity
t the real world are self-evident.
The final paper, presented by M. Guyvarcn of Aerospatiale. dealt with navigation
up-dating using map data obtained from radar. Again, the concept is to use
prc.essing power, including artificial intelligenceto obtain the necessary
correlation, in lieu of human intervention.
There really was little inter-relation among the papers in this session. They
ranged from straightforward descriptions of existing systems to discussions of
concepts that are admittedly not yet feasible. Therefore. there are no further
general comments.
2 .5 5Ssion_ I: Qpti caL Systems
Unfo-tunatel, Session IV was not accomplished as the Program Committee hadintended. Iwo of the planned five papers were. in fact. not presented. Interesting
substitute papers were arranged at the eleventh hour. However, these papers were notoarticula-ly concerned with optical systems so that the planned focus of the session
v:as regrettably lost.
he first paper, one of the substitutes, presented by Mr. Pendry of MarconiDefense Systems. concerned the operation of attack drones. One interesting pointbrought out is that drones at least offer the Potential for lower tout than missiles.
['is is pecause it nay be possible to relay environmental requirements for drones
vis-a-vis those -o missiLes since drones can be stored in environmentally controlled
containers rather than having to survive hung out on aircraft hard points. The
system concept oresented uses a beon 4ste- fr ravigation and a broadband seekerfor anli-raoar attack. It was noted that the vehicle must be falrly stealthy Since
it must *! nigh to get into oositon for a steep dive too attack. A further validvoint noted is that attaci drones have several speci c requirements. Thus, it is
not realistic to expect that the attack role can be effectively filled by a "general
purpose' drone.
he ne't caper. presented by Mr. Houston of Ferranti. was basically a history ofFe rrnti -oem e'-ve Ir the area Ox synthesis of sensor packages for target
a-, isition, detection, and designation. Past emphasis has been on television, other
sensons will be eanined in the future.
In, net 0a,-m. t-e other substitute, was presented by Mr. Fry of British
Aerospace. It concerned a low cost concept for the navigation of RPVs loitering out
of line of sight of are ground ontrol station. The concept is for the loitering RPV
to interrogate previously emplaced small low-cost beacons. With proper processing,
precise knowledge of the Deacon locations is not reduired.
The two renainirg papers in tris ses5iO were both +rom Lociheed and both
addressed developments based on the Aquila system which has completed development.
The first, presented M/ Mr. Amick addressed an attempt to reduce system cost
by introducing standardization into the development of sensor platforms, the goal of
t-' program discussed was to design a common platform for all sensors, together wIthnoncon reorograsmaole controls and Ground Support Equipment. rather than the unioue
scc ial purpose system built around each sensor. as is the case today. The result ofthe program is t-e JLCHEED ADAPTIVE MODULAR PAYLOAD (LAMPS). It would seem that
this type of Process must be undertaken if the cost-reducing benefits of
standarization are ever to oe realized,
he ninal paper or the session presented by Mr. rhompson was an evcectionally
clear presentation o1 automated search algorithms for target acquisition developedf o and -aloated in the 'I. S. crey Aouila Remctely Pilotec vehiCe system.
Because of the fragmented natJrw o this session, general comments are difficult
to nae. - -er. nere is One Point that was made imlicitly that deserves beinge olmnltl-, the point is mhat he dri~e nor standardization in an attempt to
educe osm is causing major charges in the way mirms in the aerospace industry

4
here.) Traditionally, suppliers have designed entire subsystems, such as a sensor
package, and delivered them to airframe manufacturers for integration with othersubsystems. However, suppliers cannot develop standard subsystems when they don t
know ,and will never know, because of proprietary considerations, the peculiar
requirements of their competitors equipment. Thus. only the prime contractor can
develop standard subsystems. This trend is changing the traditional roles of the
various firms in the aerospace community. The ultimate result of these developmentsis by no means clear but there is no question that the changes taking place are major
and the resultant effect n the make-up r4 both airframe comparDis and their
suppliers will be profound.
2.6 Session V: Systems External to the Vehicle
The first paper of this session, presented by M Olivier of ONEPA. was a
straight-forward comprehensive overview of ways to help maintain the data link
between RPV and ground in the prescence of various impediments to doing so.
The second paper, presented by H Hcrnfeld of MB8. dealt with using a odiital map
display as an aid in planning, control, and target position cete-iratlo-. Thesystem presented is called Intelligent Graphics Overla, System. 1509. The raner wentinto quite a bit of detail on the design of the various versions of the system.Unfortunately, however, it did not address in ver much deoth .h. the slster
characteristics are what they are. That is. what the underlying percex-ed reeds werethat led to the design decisions made. This is a very exciting area of technologxThe use of digitally generated maps for preriring, ann post-missxo. 'uo-tidnm iscontinually increasing as more and more people become aware of the tremendospotential such systems offer.
The next paper was presented b/ Dr. Carnenberg o MERIT 7S -0og._

Congress in 1988 on PRPV operations. It is Dr. Dannerberg s t-sis that f-:sdirection mandated centralized control of the launor. control. and rcoe c;Mr. Dannenberg then presented a most interesting concept for accsfoinnrr-t cxmission Dlanning function. gien that centaixzed control was.This paper produced by far the strongest emotional response c. the attendees 0

2.7 Session VI: Evaluation and Test
The first paper in this session, presented cv Mr. cek-ang or brxtm .eromace.addressed an unmanned bomber Primarily desioned +on 3ir-th- iirouJm ois-icys. Asopposed to the system discussed in paper 12 whicn addressed cr-marii, tl-e air-to-axrole. Based on the work done to-date, the author feels that ar MPV with a 0a' yr.
a man-in-the-loop, etc. is too complex for this mission. He thus adoresse, maty-role drones or autonomous aircraft acting in a role similar to that p a b a4necaircraft. ]he selected concept is for the Unmanned Aircraft cUMAs; tc be launchedfrom manned aircraft and autonomously penetrate, search. detect. ann attic. Stuieshave led to the choice of a millimeter wave radar as the target Sensor. The rangirjcapability of the radar permits setting up multiple target passes. One sensor !ofelt to be adequate since groups of targets, rather than single targets, are sougqt.
The final paper of this session, and indeed. of the svmDosium, was presented b,Mr. Ferguson of Lockheed. A very clear description of the kiomia sstem ,as
presented. The subject of the paper was tne test :)-oqram ,--led o.t Zr t- h.

3. CONCLUSIONS
The conclusions presented here are solely those of the a-thor. cased Cr the
written papers, presentations, and discussions o+ the Symposlum and on the 4rm5
handed in by the symposium delegates.
3.1 There seems to be a general consensus in the technical communlty that the
technology is in hand for a vast increase in the use of unmanned air vehicles.
Accomplishment of missions ranging from reconnaissance and sur-eillance. tmngr
logistic re-supply to areas under attaci, to autonomous attack fighter and Pomber
aircraft, seem to be becoming technologically feasible. The increasing lethalit, c
the battlefield coupled with the increasing availability of sophisticated aitonation
technology seem to make this increase in unmanned air aehicle e-rioltation
inevitable. However, this expansion of use may be limited to non-lethal missions due
to the lark of capability for aut-,umuus pony-p ilentilicatxor nf irieril -r
3.2 The US Department of Defense has signalled a significant increase in the ieel
of its interest in unmanned air vehicles by creating the Unmanned Aerial VehiclesJoint Project. However, the scope of this project is limited to non-lethal ,ehiclesso that only part of the problem is being addressed by the joint proje-t oflice.
3.3 The ever-decreasing time available for decision making, together with the ever-
increasing amount of data to be considered, mandates the use of decision aids, tas-
automation, etc. The technology for this type of automated system is increasingly
available. However, the key to Success is not the technology to do the job. butrather development of means to assure operational decision makers that they are 'on
top of" the situation and not at the mercy of a machine.

3.4 T drive for standardization as a cost reducer Is alterine the traditionalrelatit niCs of prime airframe manufacturers and sub-sNstem suppliers. More andmorr ,b-svstem .ork is being carried out by the primes themselves in the interestso. standardization. This trend, if not carefully managed, could lead to anatmosphere which stifles initiative and diversity. Standardizatio must be apolieointelligently and cooperatively, across the industry, if an atmosphere supportive o
4
innovation is to be maintained. Achieving this important goal is a challenging task.
3.5 The degree of centralization of control of RPVs is a major factor in theultimate success or failure of an RPV system. The underlying puestion here, as it sooften is, is how best to accomplish the functions of command and control.
