Our Mission

Navigation Laboratories is a provider of GPS simulators offering a wide range of products.     We have developed military grade simulators, commercial, and factory certification units. Navigation Laboratories either has, or can make, a product that will satisfy your needs.

We specialize exclusively in the construction of sophisticated GPS Constellation Simulators and Test Signal Generators.  We have developed complete turnkey systems for the following applications:

	L1/L2 P/Y military systems. This is available in various configurations from 10 to 14 channels,  with  multiple RF outputs, jamming options, pseudolite,  IMU outputs, event driven discrete I/O, antenna gain pattern modeling, and more...
	L1 C/A systems. From 10 to 14 channels with two WAAS channels, built-in jammer for MOPS testing. All vehicle motion and satellite command and control functions built in. Upgradeable to L2
	Automotive Navigation.  An all-in-view GPS signals combined with 5 VDC analog outputs that simulate a rate-gyro, analog accelerometers,  and (four) wheel speed pulse trains/odometer.  Serial bus outputs, additional 5VDC analog channels for expansion.
	GPS Integrated Inertial Navigation.  An all-in-view GPS signal integrated with strapdown IRU navigation and autopilot outputs for SDLC and differential protocol sensors such as the Honeywell HG1700 and AMRAAM. Error models provided.
	Multiple Antenna Kinematic Systems. Multiple RF outputs with relative carrier phase precisely determined, calibrated, and maintained. This allows for testing of integer cycle ambiguity and other phase dependant sensor characteristics with extreme precision.
	Pseudolite. Programmable pseudolite signals with configurable subframe data. Timing can be synchronized with live GPS satellites. Configurable pulsing algorithms and a real-time data bit editor are provided.
	Automated Test Equipment. Real-time operation via GPIB, Ethernet, RS232 using our proprietary data interface. This allows for  hands-off operation in a factory test environment or unattended operation. LabView© / LabWindows© provides an acceptable user interface.
	Closed-Loop /Training Systems. These systems use a high speed remote interface, such as GPIB, Ethernet, or ScramNet, to control vehicle flight dynamics real-time. Available as a drop-in replacement for the STel 7200 series Constellation Simulators. This system is intended for use in a multi-sensor simulation suit. Master timing signals provided or can be a slave.
	WAAS. WAAS Satellite ranging and data outputs provided. Our Waas Message Builder is used to construct and control the WAAS output data message types. Used extensively for MOPS certification testing. MOPS specified jammer included.
	CRPA Systems. We have developed the CRPA-LITE system providing individual satellite outputs on separate SMA front panel connectors. We are developing a full-up 12 channel system combined with 12 Jammer outputs (pulse, swept, gaussian, PN) with complete wavefront phase control for input into a Controlled Reception Patter Antenna (CRPA).  Satellite and jammer directionality modeling.
