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 – GPS antenna setup

Dec 25th, 2016 | By

For the installation of mine differential GPS solution with two RasPiGNSS Aldebaran modules two special GPS antennas are needed. The antennas are no classic GPS mousse with a USB connector. This antennas are special receiver modules with which only a GPS signal could be received. In each case for the base station and for the

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

Dec 25th, 2016 | By

With this post I will explain how a theoretical setup of a precise GNSS positioning architecture could look like. One essential part of the setup is the GPS base station. The base station knows her own position to less than a few centimeters exact. The mobile unit respectively the robot car is also equipped with

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
