AERPAW team worked on the manual PID tuning process of the large AERPAW UAV (the “Fat Bird”). The manual control was tightened for better responsiveness as well as reducing the limits on the maximum roll and pitch as the default was too aggressive for a drone of this size. Subsequently, the team took it out for a spin to get a feel of the result and it was deemed as flying well. The UAV breached the geofence in the end, and initiated (and completed) a return to launch, landing where it took off from.

Ground Control and Portable Node Prototype

The below figures show our current ground base station set up with a table that includes two laptops (one for setting and monitoring the UAV, the other for controlling and monitoring the companion computer).  Internet access is currently available as one of the two laptops has a cellular modem and creates a WiFi hotspot. Sun glare is a perennial problem.

The portable node prototype was manually put together after a packaging design process. RF testing of all the components has been carried out (experimental SDR, monitoring SDR, backhaul cellular modem).

December 2020

During Dec. 2020, six Terragraph radios from Facebook have been installed at CC8, CC10, CC11, and CC12, forming a daisy chain connectivity. They are being tested and expected to be available for as-is experimentation in the coming months. We have also finished installing a Keysight RF sensor on CC2 and successfully performed initial testing. We are expecting to provide remote connectivity to it during the coming months.

The first flight of a drone for Lake Wheeler Road Field Laboratories (LWRFL)

July 2020

AERPAW LWRFL Construction: Over the last few months, in a previously empty field, a hut and a tower went up, to house respectively the site distribution facility and the first radio node in the Lake Wheeler Road Field Laboratories for AERPAW. A few pictures from various points in the process are included below: the last one shows a radar drone detection experiment in progress.
