“There is an arising need in a high performance GPS on the drone autopilot market and proper antenna is critically important. We were looking to offer users of several autopilot systems (Pixhawk, APM, Navio and others) a plug and play, high performance GPS/Glonass receiver in a  form of a smart-antenna. And TW1421 will fit in this application perfectly. We are going to use the latest receiver from u-blox -  NEO-M8N.

What we have noticed, that most off the shelf GPS receivers with integrated antennas targeted to UAV autopilots never exceed SNR of 40-44 dbHz which is obviously very poor performance. As a result users experience sudden jumps in position and overall degraded navigation performance.

Compact size is another concern, on most airframes there is just no space for 100mm antenna. From our previous experience with Tallysman antennas we were able to achieve SNR of 48-50dbHz even without additional ground plane. Augmentation with additional 70mm ground plane always led to even better performance.

When we release the highest performance GPS/GNSS for SUAVs on market we will make detailed comparisons in performance with several industry standard smart-antennas(for example from 3DR) and we are absoluy confident that Tallysman will outperform them all even in 35mm compact size.”

It is always wonderful to hear such strong endorsement by a customer who has tested our antennas against competition.

I believe that Tallysman’s antennas are the best choice for UAV / UAS applications.  We have received similar endorsements from other companies involved with UAVs.
