The Reason for Tactical Data Links
NATO mandate - ADatP-31
To achieve the highest level of information exchange possible using
standard radio and telecommunications services, to provide for
command and control of forces, dissemination of the common
operational picture and resolution of information differences, withoutloss of meaning or impact.
Recent experience OP TELLIC
the main factor in our success was that we were able to function as
one team, in one fight, with one data link network.

Modern Tactical Data Links
TDL used to refer to most Bit-Oriented Radio Links integrated with
Weapons control or Command systems
In Canada, as in NATO, referred to by NATO Designator example Link-
14 In US, until recently, referred to as TADILs (Tactical Digital Information
Link) plus message designator
example TADIL-A = Link-11, TADIL-B = 11B

What are TDLs?
A TDL is an automated, interoperable information exchange method used
by allied units to provide data of tactical import for use in situation
appreciation and Command and Control.
A TDL system is comprised of computer hardware, software, media(radio), controllers, encryption devices, message standards, standard
operating procedures, sensors and operators.

Link-1
Link 1 is a duplex digital data link primarily used by NATOs Air Defence GroundEnvironment (NADGE). It was designed in the late 60s to cater for point-to-point datacommunication by wire.
exchange of air surveillance data between Sector Operation Centres (SOCs) and has a datarates of 600, 1200, 2400 bit per second (bps). It is not crypto secure and has a message set(S-series) limited to air surveillance and link management data.
Documents are STANAG 5501 & ADatP 31.
Recently been provided to NATO PfP Nations in Mobile CRCs (USAF).
Message Data
S-Series messages 128 bit packet 98 bits of Data

Link-4 (Phasing-out)
Link 4 is a non-secure data link used for providing vector commands to fighters. It is a netted, time divisionlink operating in the UHF band at 5,000 bits per second. There are two separate "Link 4s": Link 4A andLink 4C. Link4A is not encrypted. Fitted in F-14, F-16, F-18 and aircraft control units.
Link 4A is the controller to aircraft data link. Link 4C is a fighter-to-fighter data link which complementsLink 4A although the two links do not communicate directly with each other.
It is planned that Link 16 will assume Link 4A's role in AIC and ATC operations and Link 4C's role infighter-to-fighter operations. However Link 16 is not currently capable of replacing Link 4A's ACLSfunction and it is likely that Naval aircraft will remain equipped with Link 4A to perform carrier landings.
Documents are STANAG 5504 & ADatP 4.

Link-14
Link 14 is a broadcast teletype link for maritime units to transfer surveillance informationfrom ships with a computer data processing capability to non-tactical data processing ships.
provides the capability to broadcast picture compilation and status information for use inunits unable to receive Link-11 transmissions either direct or via an interface, e.g. non-Tactical Data System (TDS) units. The Link can be either HF, VHF or UHF dependent onunit-communication fits. There are some auto-plot systems capable of receiving andcharting the contacts.
Each nation within NATO has its own Link 14 transmission formats which are promulgated inADatP-14. Message protocol is defined in STANAG 5514
Message Data Character-based sequences 4-40 characters

Link-11
Link-11 is based on 1960s technology and is a relatively slow link which normally operates on apolling system with a Net Control Station polling each participant in turn for their data. In addition tothis "Roll Call" mode, Link-11 may be operated in broadcast modes in which a single datatransmission or a series of single transmissions is made by one participant. Link-11 is, therefore, a fullduplex link operated in half-duplex mode. Link-11 is secure but not ECM-resistant.
Link-11 is designed for HF (300 NM) or UHF radios (25NM), satellite media or land-line (Link-11B -
fibre-optic has been tested).
Link-11 supports the exchange of air, surface and subsurface tracks, EW data and limited commanddata among C2 units.
Within NATO Link-11 is primarily used as a Maritime Data Link. However, Link-11 will be adapted tocater for Theatre Missile Defence information exchange requirements, consequently Ground BasedSAM Systems are or will be equipped with Link-11 (or Link-11B).

Link-11B
Link-11B uses a dedicated, point-to-point, full-duplex digital data link using serialtransmission frame characteristics. Data is exchanged over a fully automatic, phase-continuous, full-duplex, frequency-shift-modulated data link operating at a standard rate of1200 bps with optional capabilities of 600 and 2400 bps.
Within NATO Link-11B is used to integrate Ground Based SAM C&C and Fire ControlCentres into the Air Defence Ground Environment using CRC SAM Interfaces (CSI). Within
the US, and some other NATO Nations (e.g. France), Link-11B is used as the primary datalink for ground based TACS (e.g. USAF MCE, and USMC TAOC).
Message standards for both Link-11 and Link-11B are defined in STANAG 5511 whilestandard operating procedures are laid down in ADatP 11.

IJMS (Phasing out)
Interim JTIDS Message Specification - came into existence because the hardwarefor JTIDS was available before the TADIL-J message standard (on which Link 16is based). Provides an initial JTIDS operating capability for the USAF and wasimplemented in the NATO E-3A, UK E-3D and French E-3F.
It is based on Link-11 messages packaged to fit into the JTIDS architecture. Samefunctionality as Link-11 but with a greater capacity and ECM-resistance.
IJMS is implemented in the UK ground environment for commonality with NATOE-3As, and the UK E-3D, while within NATO only limited IJMS capabilities havebeen implemented in NADGE CRCs. Some US fighters have a dual IJMS/Link16capability.

Link-16
JTIDS and MIDS supports three message standards: Link 16, IJMS and Variable MessageFormat (VMF). MIDS/JTIDS uses a Time Division Multiple Access (TDMA) architecture onUHF radios or Satellite.
Link 16 optimizes the use of the MIDS/JTIDS architecture. Link 16 has been developed tomeet the information exchange requirements of all tactical units, supporting the exchange of
surveillance data, EW data, mission tasking, weapons assignments and control data.TheLink 16 message standard uses J-series messages and completely meets the requirementsfor C2 functionality and aircraft control.
Numerous platforms have been or will be equipped with Link 16 (Airborne Surveillance andIntelligence Systems, C2 Systems, Fighter and Bomber Aircraft, SAM Systems, Ships, etc).
Documents are STANAG 5516 & ADatP 16.

Link-16 Development
Link-16 development started in mid-1980s with message standard and
Joint Tactical Information Distribution System (JTIDS) Class I terminals
JTIDS and later Multi-Function Information Distribution System (MIDS)
terminals combine network control, encryption and radio functions into
one device
Additional features added to JTIDS Class II and MIDS functions include
digital Link-16 voice, TACAN and IFF blanking features.
Terminals are initialized from pre-sets defined by Network planning
systems
Link-16 operational features include TDMA, so no Net Control station, jam
resistant, frequency hopping, relative navigation, secure voice and
increased data capacity over legacy data links

In most cases L16 requires a newData Link Processor (DLP) insertedbetween the Host CCS and the JTIDSand L11 terminals.
Called a C2P in the US
requires a system upgrade to interfaceto C2P

Packing and Data Rates
Effective tactical data rates of Link-16 are 26,880, or 53,760, or 107,520bits per second, depending on the data packing structure used.
Either 3, 6, or 12 words can be transmitted in a time slot, depending onwhether the Standard, Packed-2, or Packed-4 data packing (timing)
structure is used. Dense packing impacts data rate, throughput and time-slots available for
relays.

Link-22 Implementation
Link-22 is also known as NATO Improved Link Eleven (NILE)
Development started in late 1980s as improvements to Link-11
Created as a replacement for Link-11 using Link-16s J-series message data, infixed format messages needed for HF radio networks
As in Link-16, the NILE system will require a new DLP or C2P interfacing with theNILE equipment and software
USN intends to implement as a sub-set of their Link-16 system interface with aC2P upgrade
NATO IOC date is 2010
MHP and Aurora are designated Royal Canadian Air Force Link-22 growthplatforms
Royal Canadian Navy is implementing Link-22 with the Halifax ClassModernization program, with IBMs DLPS
