Wondering if it’s possible to utilize two antennas set at a fixed distance to provide fast and accurate headings for navigation. Any thoughts appreciated.
Welcome to our forum!
Typically a pair of GNSS antennas attached to the one receiver is used to calculate the heading. Such setup is standard for so-called marine GNSS receivers.
We don’t produce this type of receiver. But Reach devices can output their position via Serial, TCP, or Bluetooth in different formats: NMEA, LLH, XYZ, ENU, ERB. I’m not familiar with marine navigation software, but probably it can calculate the heading using position data from a pair of receivers.
