ANTENNA MAPPING SYSTEM
Satellite test and measurement solutions
Antenna Mapping System
Antenna Mapping System (AMS) was developed by MBI thanks to an in-depth knowledge of spread spectrum protocols in collaboration with Eutelsat, one of the world’s leading satellite operators.
AMS can be used for the measurement of radiation patterns (antenna mapping) in transmission and reception, on co and cross polar, both of the ground stations (during the tests called ESVA – Earth Station Verification Assistance) and of the antennas on board the satellites during the In-Orbit-Tests (IOT) that follow the putting into orbit of each satellite.
Antenna Mapping System was successfully tested during the IOTs of the Eutelsat 21B (November 2012) and Eutelsat 3B (June 2014) satellites and during the ESVA tests carried out at the Aflenz (Austria) teleport of Eutelsat in April 2014.
Main benefits
- Extremely low power emitted (EIRP) in order to limit interference caused to adjacent satellites / Earth Stations
- Very robust radiation pattern measurement, both against up-link and satellite down-link interference
- Measurement accuracy and stability
Auto-synchronization
AMS is able to automatically lock onto the spread spectrum signal received via the satellite. Since it can be used with negative C / N, it is not possible to use a spectrum analyzer for this purpose.
High processing gain
The band used can vary from 100 KHz to 72 MHz with processing gain up to 60 dB.
The drive chain linearity check tool allows automatic compensation of non-linearities.
