JPALS: GPS/INS Integration
To simultaneously increase the availability and integrity
of GPS and the stability/accuracy of an inertial navigation
system (INS), GPS/INS integration is an important characteristic
of an operational JPALS solution. In this regard, the following
areas are under active research:
- GPS/INS Integration Testbed This testbed
feature an array of GPS antennas, receivers and inertial
measurement units. The platform supports research work aimed
as studying GPS/INS integration methodologies for integrity
monitoring, shipboard reference station antenna motion compensation
techniques and Doppler aided tracking loop performance.
- Tracking Loops This work will study
performance of phase-locked loops for tightly-coupled GPS/INS
navigation systems, focusing on the enhancement in integrity
monitoring that can be achieved using higher-order tracking
loops in highly-dynamic vehicles.
