Maybe someone can help here. I plan to build a rover with some sensors, an UGV. First I would like to simulate the operation of a farm tractor with a GPS auto-guidance system. No easy, I know. I bought a wireless controlled car, a GPS module (Adfruit GPS with MTK3339 chipset), a gyroscope (TinkerKit T000062 2-Axis Gyro 4x) and a accelerometer (TinkerKit 2/3 Axis Accelerometer) sensors. I know that the accuracy of the GPS module is too low for this type of project, but I just want to understand the coding/programing. Later one I will try the auto-guidance with local sensors, but understanding GPS is goal now. Does anyone know about an existing similar project? any tip?
Hi PAULs, thanks for your post! looking forwards to receive the parts and start with the project. RE the accuracy, the data sheet says "(accuracy) Without aid:3.0m (50% CEP)", and in adafruit.com "Position Accuracy 1.8 meters". The idea is to simulate the operation of a farm tractor with auto-guidance system, e.g. parallel guidance. 3 m seems far too much in a real application, but the aim is to learn and to make it work (i will be using the sensors in some other stuff I guess).
