PNT That Holds
When the Spectrum Is Contested.
Critical infrastructure and moving platforms depend on GNSS for trusted position, navigation and timing. SkyTraq combines CRPA anti-jam protection, Galileo OSNMA authentication and mission-ready GNSS receivers to sustain dependable PNT across infrastructure, vehicles, vessels and aircraft—even when satellite signals are disrupted or deliberately attacked.
Built for contested spectrum.
Wideband jamming. CW jamming. Spoofed constellations. Each defeats GNSS differently. SkyTraq answers with purpose-built CRPA hardware—from an eight-element array down to a two-element board, each sized for its platform.
01
Null the jammer
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
Authenticate the signal
Galileo OSNMA verifies navigation data cryptographically, so a transmitter that imitates the constellation does not become a valid fix.
03
Fit the platform
The line runs from a 1100 g eight-element array down to a 50 g, 0.7 W two-element board, so anti-jam reaches platforms that cannot carry a full CRPA system.
Resilient-PNT Product Range
01 — Contested spectrum
CRPA Anti-Jam
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.
Resilient PNT for Essential Infrastructure and Mobility
01
Unmanned and autonomous systems
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.
02
Critical infrastructure timing
RFA-2G protects a 1PPS timing reference against interference on 0.7 W, at a size and cost that suits distributed nodes.

Why SkyTraq.
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.
- Leading product features
- State of the art performance inside the size and power envelope the platform actually has.
- High quality and reliability
- Qualified across -40 to +85 degC, and to the shock and dynamics each application demands.
- Outstanding performance to cost ratio
- Anti-jam capability priced for fleet-scale fielding rather than one-off integration.
- Fast response, world-class support
- Direct engineering contact, and firmware customized to the customer application.
