Reduction of the acquisition and tracking thresholds for carriers

Centre National d'Etudes Spatiales CNES - 10/19/2016

Description

Reduction of the carrier wave acquisition and tracking thresholds received in orbit by a satellite receiver accessing an orbital navigator, such as a Kalman lter which can be installed directly inside the receiver or ECU of the carrier satellite. The receiver is installed with a code loop, responsible for carrier acquisition or tracking. The orbital navigator is the source of the precise accuracy of the satellite receiver speed and enables the acquisition and tracking threshold to be reduced.

Benefits

Instant installation and benefits - Compatible with existing and future receivers: GPS, GLONASS, Globalstar, Immarsat, Iridium, Galileo, Compass, Egnos, IRNSS, GNSS and DORIS - Compatible with remote control receivers used in ground stations or relay satellites - No modi cation to equipment is required.

Innovations

Improved carrier acquisition - Significant reduction of the acquisition and tracking threshold for carrier waves - Reduced acquisition time - Improved robustness of geostationary satellites and satellites in survival mode Compatible with all types of satellite - Compatible with LEO, MEO, GEO or HEO geostationary satellites.
