What do we consider Precise GNSS?
• Currently Usable Constellations
• GPS (USA) – 30 sats
• GLONASS (Russia) – 21+ sats
• Future Constellations include:
• Galileo (Europe) – now 4 sats
• BeiDou (China) – now 14 sats
• It is differential processing (DGPS, RTK) or PPP
• It can be real time or post-processed
• It is nearly always relative !!!!!!!

More constellations
More signals
More applications
![Page 19: Precision GNSS in the Asia-Pacific Region€¦ · • GPS (USA) – 30 sats • GLONASS (Russia) – 21+ sats • Future Constellations include: • Galileo (Europe) – now 4 sats](https://reader036.fdocuments.in/reader036/viewer/2022071010/5fc81612dbbd2b4b163d3e9b/html5/thumbnails/19.jpg)
BEIDOU • Chinese Beidou system reached
Asian regional coverage in late 2012 with 4 Geostationary, 6 Geosynchronous and 4 MEO satellites. Full global operations of 30 satellites by 2020.
![Page 20: Precision GNSS in the Asia-Pacific Region€¦ · • GPS (USA) – 30 sats • GLONASS (Russia) – 21+ sats • Future Constellations include: • Galileo (Europe) – now 4 sats](https://reader036.fdocuments.in/reader036/viewer/2022071010/5fc81612dbbd2b4b163d3e9b/html5/thumbnails/20.jpg)
• BeiDou coverage in South Asia sees all 14 Satellites, but
Poor DOP due to Geo’s “stuck” in the North segment.
![Page 21: Precision GNSS in the Asia-Pacific Region€¦ · • GPS (USA) – 30 sats • GLONASS (Russia) – 21+ sats • Future Constellations include: • Galileo (Europe) – now 4 sats](https://reader036.fdocuments.in/reader036/viewer/2022071010/5fc81612dbbd2b4b163d3e9b/html5/thumbnails/21.jpg)
• However GPS+GLONASS+BEIDOU coverage is very good
![Page 22: Precision GNSS in the Asia-Pacific Region€¦ · • GPS (USA) – 30 sats • GLONASS (Russia) – 21+ sats • Future Constellations include: • Galileo (Europe) – now 4 sats](https://reader036.fdocuments.in/reader036/viewer/2022071010/5fc81612dbbd2b4b163d3e9b/html5/thumbnails/22.jpg)
• Novatel is selling
GPS+BeiDou and
GPS+GLONASS+BeiDou
systems for data and RTK
• Shows better availability
and integrity for RTK
• Interest shown from Mining
& Construction groups

Space Weather Monitoring • GNSS based monitoring
− Global basis, all-weather and continuous fashion
− Constellation: multiple pierce points
• Ionospheric measurements − Refraction: Total Electron Content (TEC) unit
− Scintillation: Amplitude (S4) and phase ()
• Challenges − Phase: Receiver oscillator phase noise
− Amplitude: Multipath fading
− TEC: Semi-codeless L2 P(Y) tracking
− Narrow loop bandwidths
