What is GISS?
Download book in PDF, 5MbGISS SERVICE AREAS
The calculation of the GISC service areas is based on the condition:
- the orbital constellation contains 288 spacecraft,
- the height of the circular orbit is 800 km,
- SC are in 12 orbital planes, 24 SC of two types, following each other,
- the angle between the planes is 15°,
- the angle forming the visibility zone (the satellite antenna cone) – 61°.
In the Zones with the area of simultaneous coverage by two spacecraft, communication services are provided in both L- and X-bands.
In areas with an area of simultaneous coverage by three spacecraft, communication services are provided, with the possibility of two-fold duplication of lines for receiving and transmitting information in both L- and X-bands.
In areas with an area of simultaneous coverage of four spacecraft, radar detection and high-precision positioning in both L- and X-bands are provided. When providing communication services, with the possibility of three-fold duplication of information receiving lines.
