NavStorm™+ GPS Receiver

A small, low power, G-hardened, SAASM-based GPS receiver with integrated five-channel anti-jam. Currently used on major weapons systems for precision guided artillery and bombs.

In today’s unpredictable battlespace, launching weapons safely and accurately is critical to mission success. NavStorm™+ is a 24-channel, dual-frequency, all-in-view receiver capable either as a stand-alone system or integrated with an Inertial Navigation System (INS). Powered by state-of-the-art technology, NavStorm+ provides enhanced, Direct-Y acquisition, built-in digital nulling for high jamming immunity (>92 dB J/S while tracking) and fast initial acquisition. NavStorm+ is the first fully qualified, integrated GPS and anti-jam system in the proven family of Collins Aerospace gun-hardened GPS receivers for weapons.
