TruTrak-M HDA

Overview

This receiver excels at navigating and tracking GPS signals from Earth’s surface to orbital altitudes at hypersonic speeds, delivering both a position, velocity and time solution and line-of-sight observables. The HDA has flown around the Earth, delivering exceptional accuracy and dependability. Engineered to meet the demands of the most challenging missions, the TruTrak-M HDA stands out as a reliable and accurate navigation solution.

Key Features and Benefits

  • Compact Design: Utilizes the Type II form factor with specialized software tailored for space applications as well as high dynamic applications
  • MGUE Standard Connector: Utilizes the 80-pin I/O connector in line with MGUE standards
  • Dual Frequency: Tracks C/A, Y and M signals on both L1 and L2 frequencies for robust navigation
  • Super High-Altitude Navigation: Accurate navigation at altitudes up to 8000 Km
  • Line-of-Sight (LOS) Observables: Delivering line-of-sight (LOS) observables, including Pseudorange and Carrier Phase at 10 Hz
  • Position, Velocity and Time (PVT) Data: Outputs PVT data at a frequency of 10 Hz for enhanced performance
  • Direct Signal Acquisition: Enables the direct acquisition of Y and M signals
  • Field Reprogrammable: Incorporates a field reprogrammable design, allowing for future updates with minimal disruption to system operations
  • Security Certified: Fully security certified and approved, supporting unclassified when keyed operations
