This site is devoted to the development of a new tactical communications messaging protocol inspired by Bob Bruninga's APRSTM protocol.

OpenTRAC stands for Open Tactical Reporting and Communications. In short, it's a message protocol designed for carrying tactical information, including GPS position reports, weather data, and telemetry, over an unreliable, bandwidth-constrained network. Typically, this is the Amateur 2-meter VHF band using 1200 bps AFSK. The protocol is specifically designed, however, for use across multiple networks to support Internet backbones, satellite links, and so on. For more detailed information, check out the introduction to OpenTRAC.
