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

2. Demonstrated with a good external LNA

3. For hot start, all sats have the same signal level except one (pilot sat @-145 dBm)

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

5. For GALILEO the signal level refers to both pilot and data components

6. Configurable value

7. All satellites at the same signal level
