I am part of a UAV lab NIMBUS lab. We were looking to equip our fleet of UAVs with RTK systems. I am currently evaluating them. We are located in Lincoln, Nebraska, USA.
The first challenge we encountered was not being able to setup Wi-Fi using Windows 10. A Wi-Fi connection was setup using VMWare and Ubuntu while following the steps from this site: Intel Edison. We use a ZyXEL router as an IP address distribution device.
An Odroid XU4 attached to an Ascending Technologies Hummingbird running ROS nodes is used to pass data from/to the rover. It was assumed one could use the micro-USB connection between the Reach and the Odroid. After discovering that was not the case, a uart-to-USB connection was used to connect the Reach and the Odroid. Radios used are paired XBee Pros connected to SparkFun USB boards.
Yesterday the rover device became unreachable twice, this happened once today as well. I unplugged and replugged the USB device each time and eventually was able to access ReachView again.
While testing near soy bean plants with a clear sky, we had low GPS signal strength with at most 2 satellites reaching a green ReachView level at one time. Screenshots from those tests were not taken. The Reach devices are several meters apart during our most recent tests. The antenna from the Reach kit is attached to the base Reach device with no additional amplification and placed on the ground during the tests. The following ReachView screenshots were taken from a space where members of the lab routinely fly. The space is relatively close to our lab.
What configuration settings must be changed to receive stronger signals? What must be done to receive stronger signal strength with Reach devices? The following images are of the configuration settings during our most recent tests.
Here is a link to the UBLOX protocol. Someone on the forum wanted to decode ECEF.
