NavCom Technology

NavCom Technology is a leading developer of advanced GNSS solutions for systems integrators and OEMs of UAVs (unmanned aerial vehicles) and other unmanned platforms that require high-performance, precise positioning solutions.

Our expertise in such technologies as base station-free augmented precise point positioning, navigation engine development, and OEM integration support have led us to develop innovative solutions that are ideal for autonomous vehicle control and other robotics applications.

StarFire™ Global Correction Service

Precise Point Positioning (PPP) for Navigation Systems

StarFire GNSS Correction Service

The StarFire™ Global Correction Service provides real-time GNSS satellite orbit and clock corrections that result in positioning accuracy of typically better than 5cm (<2 inches). Calculations are performed by a network of more than 40 GNSS reference stations around the world, and the results broadcast by geostationary satellites. Coverage is virtually worldwide (from 72ºN to 72ºS latitude) and enables precise real-time navigation without the need for local ground base stations.

The highly robust system boasts an uptime of 99.999% and utilises redundant data links, geographically separated processing hubs, and dual satellite uplink equipment to ensure continuous service. Superior accuracy is provided by considering each signal error sources independently, and StarFire™ outputs one set of corrections for the entire world, giving it a distinct advantage over traditional differential GNSS (dGNSS) systems.

In addition to the standard StarFire™ subscription service, NavCom also provides select StarFire™ Reference Data to customers in more specialized application areas such as drone survey post-processing, military mission planning and navigation simulation, and location-based services:

  • Real-time GPS Satellite Data (SV Ephemeris Data) – enables low cost L1 GPS chipsets to acquire position in 6 seconds instead of the typical 1 minute
  • Real-time StarFire™ Corrections – provides L1 chipsets with significantly greater position, improving from ~30m to 1.5m
  • Real-time Satellite Data & Corrections – enables position acquisition in 6 seconds as opposed to 1 minute and improves accuracy to 1.5m as opposed to ~30m
  • Real-time Timing Reference Data – low cost, high-resolution alternative to current timing elements that exceeds the cellular infrastructure provider requirement of 7 microseconds with a provided resolution of 12.5 nanoseconds
  • Archived Satellite Data & Corrections – allows post-processing of measurement data to achieve millimeter-level accuracy.

Onyx OEM GNSS Board

Integrated StarFire™/RTK GNSS Module

Onyx OEM GNSS Board for UAVsThe Onyx is NavCom’s next-generation GNSS engine that provides 255-channel high sensitivity/low signal level tracking and multi-constellation support (GPS, GLONASS, Beidou, Galileo). With a compact form factor and integrated StarFire™ technology that provides global positioning to five centimetres, Onyx is ideal for high accuracy surveying applications, as well as control and guidance of unmanned vehicles such as UAVs.

StarFire™ is supported on 3-separate channels providing on-board capability for tracking redundant or enhanced signals. Onyx also features patented interference rejection and anti-jamming capabilities.
