Sensing & Navigation using a RTK and GPS

rtk_gps

A RTK GPS was used to collect and analyze the measurement data from the sensor. The data was collected by walking through various parts of the city. The minimal effect of obsructing buildings was noted and compared to the data collected from traditional GPS.

Required

• RTK GPS
• GPS Antennas
• Reach Emlid boards
• Python 3

Setup

RTK Rover Setup:

1. Pick a rtk as rover and connect it to your laptop through USB port. Now, connect the radio and reach through UART. A red light will turn on when your rover is still initializing. If the radio boots up correctly, a blinking green light will take the place, indicating that it’s searching for its paired radio.

2. When reach is powered up properly, it goes into hotspot mode and broadcasts a hotspot named as reach:xx:xx. The default password is emlidreach.

3. Once you connect to hotspot successfully, go to http://192.168.42.1 in the browser. You will see a website showing the device’s status.

RTK Base Setup:

1. Now boot up the other reach as your rtk base. It’s almost the same to rover gps, just that you don’t have to use the USB port on your laptop as power source since you are not gathering any data from a rtk base. Similar to setting up a rtk rover, you need to connect to the hotspot of the device and check some configurations.
