LAUNCHPAD OEM GNSS INS INTEGRATION TESTING DYNAMIC TESTING BEFORE FLIGHT The CAST 3000 fully supports integration testing of GNSS INS navigation systems where the inertial sensor and GNSS receiver are either tightly or ultra tightly coupled It produces GPS RF signals coincident with simulated IMU sensor data that provide dynamic testing in the laboratory environment for military and government applications The proprietary laboratory test interfaces to inertial navigation products of both Honeywell and Northrop Grumman are incorporated with high performance fighter aircraft and munition dynamics The Ground Uplink Subsystem Precise Clocks Orbits Processing Center L Band Satellite Delivery Global Station Unmanned NovAtel Customer Agriculture Ground Mapping ION GNSS 2016 EXHIBITOR 14 GPS WORLD WWW GPSWORLD COM SEPTEMBER 2016 CAST 3000 simulates dynamics for both the GNSS and INS portions of EGI embedded GNSS inertial navigation systems in a coordinated and coherent way so that the GNSS and INS navigation solutions do not diverge and the blended solution is precisely what it would be in the real world This is accomplished by simulating both the GNSS and INS inputs The military and government labs that the CAST 3000 supports have strict requirements for dynamic ground testing of navigation systems before flight testing The simulator must explore performance of both GNSS and INS aspects of the EGI for modeling IMU drift rates in GPS jamming environments CAST Navigation www castnav com CAST 3000 FEATURES Strapdown IMU measurement data synchronized with GPS RF data provided to the navigation system under test Mature avionic sensor simulation barometric altimeter model High rate inertial measurements with very high degree of fidelity to support testing of high performance coupled systems Simulates sensors to provide the fully coordinated dynamic vertical channel aiding needed to maintain Kalman filter stability of the navigation system Includes years of development and refinement of the precise GNSS INS synchronization capability needed for simulation of aircraft dynamics A dynamic precisely coordinated simulation of numerous navigation signals to a tightly coupled or ultra tightly coupled GNSS INS navigation system POSITIONING ENGINE INCORPORATES TERRASTAR CORRECTION DATA NovAtel CORRECT is the core positioning engine on NovAtel GNSS receivers incorporating corrections from a variety of sources to provide the position solution suitable for a variety of applications NovAtel CORRECT with PPP utilizes correction data from TerraStar GNSS satellite clock and orbit correction data from the TerraStar network is delivered directly to the NovAtel receiver where it is combined with NovAtel CORRECT algorithms to offer two levels of positioning accuracy TerraStar C for 5 centimeter level positioning with instant reconvergence after short GNSS outages and TerraStar L with horizontal position accuracy of 50 centimeters The TerraStar network provides continuous satellite coverage worldwide with 80 GNSS reference stations located around the globe Three widely distributed Network Control Centers deliver data over seven independent satellite beams This fully redundant system means TerraStar offers an extremely robust reliable correction service users can rely on 24 7 NovAtel novatel com terrastar BENEFITS OF NOVATEL CORRECT WITH PPP Elimination of base station and communications equipment simplifying equipment needs Same performance anywhere on Earth Robust performance in variable conditions Corrections delivered direct to the end user ION GNSS 2016 EXHIBITOR NovAtel CORRECT with PPP
