The Carrier ID is transmitted using spread spectrum technique.

At Satellite Monitoring facilities, the carrier ID is demodulated to findthe contact information and quickly point out the source of interference or to check transmitter compliance with CID regulation.

Purposes:• To improve geolocation accuracy;• To secure the satellite with the surrounding

environment;• To retrieve measurements quickly after maneuver;• To ensure rational, equitable, efficient and economical

use of the frequency and satellite orbit;• To preserve performances, interoperability and quality of

satellites communications…



Satellite Ephemeris Estimationby ZODIAC DATA SYSTEMSSatellite Ephemeris Estimationby ZODIAC DATA SYSTEMS

SEE concept:

• 3 Rx Stations minimum to receive Payload & GNSS signals

• Payload signals are correlated to retrieve TDOA measurements between stations

• TDOA delivery is done in less than10 seconds.

(TDOA :Time Difference Of Arrival)

SEE provides TDOA measurements based on Passive Ranging
