Precise GPS GNSS positioning with a Raspberry Pi and the RTKLIB – XBee serial data transmission

Feb 2nd, 2017 | By

With an XBee module different network topologies could be setup. I only use a direct connection between two XBee modules for my differential GPS setup. This connection mode is pre-configured and works out of the box without any configuration from your side. It is possible to configure the for example the network name. This is

Precise GPS GNSS positioning with a Raspberry Pi and the RTKLIB – software installation

Dec 28th, 2016 | By

This chapter explains which software needs to be installed on your Raspbian installation to get the RasPiGNSS Aldebaran module which should now be mounted on top of your Raspberry Pi working. For this explanation I will use Raspbian as operation system. I am using the Raspbian version “2016-09-23-raspbian-jessie.img“. From my experiences I would suggest that

Precise GPS GNSS positioning with a Raspberry Pi and the RTKLIB – introduction

Dec 23rd, 2016 | By

A few years ago I started building robot cars which could drive in my living room or outdoors. Some of the vehicles are equipped with a standard USB GPS mouse. But I was again and again disappointed how inaccurate the received GPS position from an USB GPS mouse is. The accuracy of the position received

Raspberry Pi self-driving car 13

After two years of work I finished my self-driving robot-car. The robot is able to navigate and to autonomously drive around in the garden. It is equipped with different sensors and the combination of the sensors information enables the robot to drive around. The first self-driving robot was the Discoverer which is equipped with a
