PSEUDOLITE / GROUND TRANSMITTER
The NAVLABS DS_400 Digital Simulation Engine has pseudolite generation capability built in from first article.
To be used as an actual pseudolite, the NAVLABS DS_400 supplies many, but not all of the needed components. In addition to 4 (or more DS_400 GPS Engine) THE FOLLOWING ELEMENTS ARE REQUIRED:
- Time Transfer GPS receiver. These are commercially available. They oputput a 1-PPS slaved to the GPS one-second rolloever and supply the epoch per TCIP.
- A Signal Amplifier and Broadcast system
Given the above caveats, we've participated in a proof of concept as follows:
