1. All satellites at -130 dBm - TTFF at 50%.

2. For BEIDOU tracking sensitivity refers to MEO sats. For GEO the tracking sensitivity is -151 dBm.

3. With external LNA.

4. CEP 50%, 24h static, roof antenna.

5. To be compliant with USA International traffic in arms regulations (ITAR), when both the ITAR altitude limit and the ITAR

velocity limit are overpass taken the Teseo-LIV4F stops providing NMEA stream.
