Santa Rosa, Calif. - PNI Sensor has announced two new navigation tools designed for engineers building resilient PNT solutions: the FORT Field Ops Remote Tracker for true GPS-denied edge-AI tracking, and the SeaTRAX-85° Towed Array Heading Sensor for accurate heading in polar marine environments.
FORT: EDGE-AI TRACKING WITHOUT GPS OR RF BEACONS
PNI Sensor’s FORT (Field Ops Remote Tracker) is a body-worn positioning and tracking device that works indoors or out, including in contested environments where GPS is degraded, denied, or impractical. It applies PNI’s Continually Adaptive Navigation (CAN) algorithms to reduce drift and mitigate magnetic interference.
FORT is 100% self-contained and non-jammable, avoiding the drift and magnetic-interference failure modes common to legacy sensor-only tracking systems. Its edge-AI sensor fusion approach does not depend on cameras or RF beacons that can be occluded, and it requires no external signals that can be jammed, spoofed, or otherwise disrupted.
PNI’s CAN-augmented tracking is designed to deliver approximately 10 meters of positional accuracy per kilometer traveled, without GPS or RF beacons.
Designed as a practical, cost-effective PNT element for assured PNT and MGUE-related architectures, FORT gives navigation system engineers a deployable tracking node for maintaining navigation continuity under electronic attack and in infrastructure-limited environments. Recognized by the U.S. Department of Defense as an xTechSearch 7 award winner, FORT directly addresses demand for compact, resilient assured PNT at the edge.
SEATRAX-85°: EXTREME-LATITUDE HEADING FOR MARINE MISSIONS
Conventional magnetic heading solutions can accumulate large errors within minutes when used above the Arctic Circle due to near-vertical field lines and degraded sensor observability. SeaTRAX-85° is PNI’s new towed array heading sensor, engineered specifically for accurate headings in extreme latitudes, including operations near the poles.
SeaTRAX-85° delivers 0.25° heading accuracy within the Arctic Circle and better than 1.5° at 85° latitude, enabling clean survey lines, stable tow-fish orientation, and reliable platform control in Arctic waters and other high-latitude operating areas. This gives marine system designers a heading reference that remains usable where traditional magnetic solutions quickly break down.
PNI Sensor Company
PNI Sensor has a long track record in navigation, providing precision navigation and heading solutions that combine proprietary sensors, algorithms, and edge intelligence for mission-critical applications. Its portfolio supports military, space, and underwater systems where GPS is degraded, denied, or unavailable, with a focus on field-ready resilience for assured PNT.
PNI works closely with engineers, operators, and platform integrators deploying systems in contested and infrastructure-limited environments.
