The most demanding defense and aerospace applications require the most robust and capable navigation solutions. VectorNav’s Tactical Series is designed to provide unprecedented modularity with support for a range of external inertial and positioning technologies. Complete your objective and gain the competitive edge over emerging Navigation Warfare (NAVWAR) threats and contested environments with VectorNav.
VectorNav’s Tactical Series features auxiliary ports to connect to external Inertial Measurement Units and SAASM or M-Code GPS receivers. The extended capabilities of the Tactical Series enable users to take advantage of VectorNav’s superior navigation algorithms while incorporating other technologies to enhance capabilities, security and performance in contested environments.
Additional capabilities enabled by external IMUs and SAASM or M-Code receivers are:
Applications that require precise positioning when operating in contested environments require the latest developments in modernized GPS with anti-jamming/anti-spoofing capabilities and increased security. Legacy SAASM (Selective Availability Anti-Spoofing Module) GPS receivers are being updated to M-Code receivers that feature greater anti-jamming and security. VectorNav’s Tactical Series supports any GPS/GNSS receiver that is configured to output GPS-ICD-153 protocol. Simple connection of power, ground, serial communication lines and 1PPS to the auxiliary port on the Tactical Series device will enable the sensor to utilize the external PVT data for its INS solution.
VectorNav Tactical Series currently supports three external IMUs. The table below provides a brief summary of their specifications.
