BAE SYSTEMS to develop an integrated mems INS / GPS system for the military market

23 Jul 2002

BAE Systems and Rockwell Collins have signed a collaboration agreement for the development of SiNAVTM, an integrated MEMS INS/GPS system for the military market. The fusion of leading MEMS inertial and SAASM GPS technologies offers customers a total navigation solution representing a breakthrough in terms of affordability, size and gun-hardness. The product is initially focused on meeting the demand from the guided munition and projectile market, with numerous other military applications for such a capability emerging.

SiNAVTM integrates the MEMS inertial engine of the BAE Systems SiIMU01TM with the Rockwell Collins NavStormTM military P(Y)-code SAASM GPS receiver to produce a closely-coupled navigation system. A multi-phase development roadmap for the SiNAVTM evolution introduces technology advancements in Silicon MEMS IMUs and SAASM GPS as they become available, and focuses on deep integration to enhance performance, reduce size and minimise cost.

Note to editors:

SiNAVTM is the product of fusing the BAE Systems SiIMUTM and Rockwell Collins NavStormTM technologies. SiIMUTM and NavStormTM are highly successful products in their own right.


SiIMUTM is an all micro-machined silicon Inertial Measurement Unit (IMU) developed by BAE Systems Inertial Systems Division at Plymouth, England. SiVSG Micro-machined Electro-Mechanical System (MEMS) rate sensor technology is the result of over 15 years research and development. This revolutionary solid state sensor technology is a breakthrough in gyro system affordability and robustness, enabling inertial guidance and control of next generation, gun-launched, guided weapons to be realised. SiVSG is in high volume production (3 million per year) for commercial as well as military applications. SiIMUTM has been selected for such programmes as Vertical Launch Seawolf (VLSW), Extended Range Guided Munition (ERGM), Advanced Gun System (AGS), Longbow, Next Light Anti-tank Warning (NLAW), Low Cost Precision Kill (LCPK) and Rolling Airframe Missile (RAM).


The Rockwell Collins NavStormTM Global Positioning System (GPS) receiver is a gun-hardened 12-channel Selective Availability Anti Spoofing Module (SAASM) based, GPS embedded module. The NavStormTM has been designed to withstand the extremely severe environment of artillery applications through the incorporation of a gun-hardened variant of the Rockwell Collins SAASM module and an artillery GPS oscillator design. Its compact form factor enables very dense electronics packaging for the development of miniature GPS navigation systems. The NavStormTM is ideally suited to tightly coupled GPS/Inertial Navigation System (INS) systems for artillery or other applications requiring a highly ruggedized product. Rockwell Collins began delivering fully capable NavStormTM receivers in mid-2001. NavStormTM has been incorporated on numerous GPS developmental programmes with gun-hardened requirements including Low Cost Guidance Electronic Unit (LC-GEU), AGS, FASM and Barrage.
