Build Robot Cars with the RasPiGNSS

One of our customers is building wonderful things with the RasPiGNSS. Ingmar Stapel builds robot cars based on the Raspberry Pi and the RasPiGNSS. For precise navigation two RasPiGNSS are used in RTK mode, one set up as a fixed base station, while the other one is mounted on the robot car (rover), using RTKLIB to compute a precise RTK GNSS solution. The setup and installation of hardware and software is explained in detail at custom-build-robots.com/elektronik/praezise-gnss-positionierung-mit-dem-raspberry-pi-und-rtklib-einfuehrung (in German). Check out his website at custom-build-robots.com for more information!

Compatibility testing with Raspberry Pi 3 completed

Compatibility testing with the new Raspberry Pi 3 model B has just been completed. The RasPiGNSS “Aldebaran” module is fully compatible to the Raspberry Pi 3. Since there was a hardware change on the Raspberry Pi 3 concerning the serial port on the P1 GPIO header, some configuration work needs to be done in order to make the RasPiGNSS work. The installation section has been updated to reflect this change. Please carefully read and follow these instructions in case you want to use the RasPiGNSS on a Pi 3.

RasPiGNSS successor "Aldebaran" in production

We are excited to announce that the successor of the successful RasPiGNSS “Cook” device is now in production. The RasPiGNSS “Aldebaran” GNSS expansion board exhibits the same features - and some more - as the “Cook” device, while staying nearly 100% hardware- and software compatible. The only omission is the magnetic reed contact, which has hardly ever been used. The board design has been improved to fit the layout of the Raspberry Pi A+ and B+ models, such that it can now be stacked and even secured with mounting screws and spacers directly to the Raspberry Pi board.

The RasPiGNSS “Aldebaran” features:

  • The latest version of the NVS NV08C-CSM GNSS chip (currently v4.1), compatible with the GPS, GLONASS, GALILEO, and BEIDOU satellite systems.
  • Three red/yellow/green status LEDs, now with improved luminosity.
  • Two tactile push-buttons.
  • A connector to the second UART port of the NV08C-CSM, allowing external connection to other devices needing position information, e.g. for drones.
  • A display connector allowing the connection of a HD44780-compatible LCD display, e.g. for immediate position and status display on the device itself.
  • An I2C connector allowing the connection of any I2C device like RTCs, IMUs, ADCs, etc., with nearly endless possibilities. I2C pull-up resistors are also provided, which may be enabled through solder jumpers on the board if needed.
  • An SPI connector allowing the connection of any SPI device like ethernet or WiFi cards, generic MCU programming, etc.

We will publish information on how to use all those new exciting features of the board after the board is available for purchase. We expect the RasPiGNSS “Aldebaran” to be available for purchase in the online shop within the next few weeks - all at the same price as the previous RasPiGNSS module. If you have any questions, please don’t hesitate to inquire.

New release of RasPiGNSS tools

A new version of the RasPiGNSS tools has just been released, which now features the addition of a nmeaparse command that provides a live view of the receiver solution status, errors, and satellites in view and used for computation of the solution. This enables to get a quick overview of the satellite constellation as well as receiver and antenna performance. Find more information about this new tool in the installation and FAQ sections.
