From CRPA anti-jam systems and high-dynamic receivers to gun-hardened GNSS chipsets, SkyTraq delivers resilient PNT for contested signals, supersonic flight, and extreme shock.
Jamming. Supersonic flight. Gun-launch shock. Each challenges GNSS differently. SkyTraq answers with purpose-built hardware—from CRPA anti-jam systems and high-dynamic receivers to gun-hardened chipsets, each sized for its platform.
01
An 8-element CRPA forms up to 7 independent nulls and holds 39 dB of suppression with seven wideband jammers running at once. Against a single CW jammer it exceeds 65 dB.
02
Galileo OSNMA verifies navigation data cryptographically, so a transmitter that imitates the constellation does not become a valid fix.
03
A 5 x 5 mm QFN40 chipset qualified for G-hardening reacquires in under 2 seconds at 1300 m/s after a 60 second outage, and tracks to 2000 m/s.
01 — Contested spectrum
Controlled reception pattern antenna receivers that steer nulls onto jammers as they appear and authenticate Galileo OSNMA against spoofing. Each unit also outputs jammer-removed RF, so an existing receiver behind it keeps working without being redesigned.
8-element CRPA, 7 nulls
Plug-and-play anti-jam receiver for mass deployment across unmanned and autonomous defense systems. The 8-element array forms up to 7 nulls to defeat multi-source wideband jamming, and with Galileo OSNMA anti-spoofing.
5-tap STAP CRPA
Space-time adaptive processing across a two-element array, using five taps per element to null jammers in time as well as space. Cost engineered for high-volume applications.
2-element CRPA board
Low-cost, low-power dual-element CRPA on a single board, forming a null against the dominant interferer with 0.7 W power consumption. Suitable for applications requiring small size, light weight CRPA.
02 — High-velocity flight
A 10.1 x 9.7 mm L1 multi-constellation module that holds position, velocity and timing through supersonic flight, rated to 1000 m/s and 4 G.
Supersonic GNSS module
L1 single-frequency receiver for supersonic defense platforms, tracking GPS, GLONASS, Galileo, BDS and QZSS to 2 m CEP in a module small enough for the airframes that fly fastest.
03 — Gun-launched munitions
A 5mm x 5mm QFN40 GPS receiver chipset for g-hardened 155 mm artillery and other cannon-launched precision munitions, designed to have fast TTFF on the way out of the tube
GPS chipset for G-hardened precision guidance
5 x 5 mm QFN40 GPS chipset for precision guidance kits. First fix lands about 7 seconds after launch at 1300 m/s muzzle velocity on a 40 dB-Hz signal, and about 10 seconds on 35 dB-Hz.
Custom application
The defense range is built on the same 5 x 5 mm QFN40 GNSS chipset. Firmware is customized to the application, and the same silicon forms an L1, L1/L2, L1/L5 or L1/L2/L5 receiver.
L1
GPS/QZSS L1, GLONASS L1, Galileo E1, BDS B1I signal reception.
L1/L2
GPS/QZSS L1/L2C, GLONASS L1/L2, Galileo E1/E5b, BDS B1I/B2I signal reception.
L1/L5
GPS/QZSS L1/L5, Galileo E1/E5a, BDS B1I/B2a, NavIC L5 signal reception.
L1/L2/L5
GPS/QZSS L1/L2C/L5, Galileo E1/E5a/E5b, BDS B1I/B2I/B2a, GLONASS L1/L2, NavIC L5 signal reception.
Fleet-scale anti-jam PNT for UAS, UGV and USV. AJAS-8 and AJAS-2 field as plug-and-play units, so the platform's existing receiver does not have to be redesigned around them.
PX100-0S-PGK carries the guidance fix through 155 mm gun launch, acquiring at supersonic velocity on the way out of the tube.
Orion C10-S1 holds position, velocity and timing to 1000 m/s and 4 G in a 10.1 x 9.7 mm module.
RFA-2G protects a 1PPS timing reference against interference on 0.7 W, at a size and cost that suits distributed nodes.
A GNSS silicon house, not a systems integrator reselling someone else's receiver. The chipset, the firmware and the anti-jam processing are all ours, which is why the size, power and cost land where they do.
