    Overview Javad Navigation System's LGG100-GG is a single frequency, GNSS receiver built to be advanced and compact receiver for LGG100-GG for following mar- kets: navigation, aviation, timing, oil platform positioning, land, air and sea transportation, personal location and tracking, highway navigation and guidance etc.
  • Page 17: Principles Of Operation

    Once the receiver locks on to a satellite, it starts recording measurements and receiving various digital information (ephemeris, almanac, and so on) the satel- lites broadcast. To calculate a position, receivers use the following formula: Velocity x Time = Distance www.javad.com LGG100-GG Operator’s Manual 17...

    • Integrity – Fault tolerance allows a position to have greater integrity, increasing accuracy. Several factors combine to provide fault tolerance, including: –Receiver Autonomous Integrity Monitoring (RAIM) detects faulty GPS and GLONASS satellites and removes them from the position calculation. 18 LGG100-GG Operator’s Manual www.javad.com...
