Baltimore-based ADCOR MAGnet Systems LLC has launched a Kickstarter campaign for its new drone technology, the Pharos smart antenna, an electronically controlled tracking antenna with no moving parts.
According to the company, the antenna – working in conjunction with Pixhawk autopilot – forms a directional, high-gain beam and keeps the drone always pointed to the ground control station (GCS), regardless of the aircraft’s motion.
Unlike conventional, omni-directional antennas that waste energy in all directions, says ADCOR, the Pharos concentrates the available power where the user needs it most. In addition, Pharos is also circular-polarized and grants immunity to polarization losses and multi-pathing signals.
The company says the antenna can be used with any type of robotic platform that needs an extended data link.
According to ADCOR, possible uses of the antenna are as follows:
- Use it with a 5.8 GHz video transmitter on a Pixhawk-equipped drone (aerial side for improving video transmission);
- Use it with a 5.8 GHz video receiver on the ground by interfacing it to a Pixhawk controller (ground side for improving video reception); or
- Use it in conjunction with a Microhard 5.8 GHz modem on both the drone and the GCS for improving both telemetry and video streaming.
