Max2769: RTK GPS for all?

Here we go again.

Like mp3 encoders before LAME, RTK GPS based on inexpensive GPS receivers & software has long been a dream that no-one has been able to get working.

For years, a Japanese team has used a discontinued uBlox module that costs just as much as a commercial RTK GPS solution.  Now the latest hobbyist movement is to use just the GPS front end &…

DGPS with NMEA messages for DroPix flight controller + Intel Edison

We are currently working on a DGPS solution for UAVs to improve precision up to centimeter levels. Our architecture is the following, we use two Ublox GPS with raw data activated, one for the base station, the other one for the rover. The rover GPS is connected to the Intel Edison breakout board that also receives the base station GPS signal through a telemetry (for the moment, we are also focusing on a 2G/3G/4G solution that would remove all range problems). Then, the Intel Edison runs the…

For the first time since Mike Fouche documented it on Goo Tube.

An autonomous copter has flown at a certain very high altitude in a certain country. The exact altitude & country is a secret to protect the innocent of course. It was also at midnight, like all our most extreme test flights.

Since the radio seems to work… Continue

Reach RTK GPS can now embed ground control points in imagery

From the blog of the Pixahwk-compatible high-accuracy Reach RTK GPS 

Reach was built with precision mapping applications it mind. One of the big challenges in UAV mapping is eliminating Ground Control Points which are time consuming and costly to place. Reach RTK can help achieve that by synchronizing with the camera shutter on sub…

RTK GNSS module build

I just realized this is the very first blog I ever wrote :) 

RTK GNSS is an interesting topic for many quadrotor diyers like myself. It can provide stable sub meter coordinates which is very attractive for autonomous quadrotor flights. Initially, I tried RTKLIB on windows platform, and the result is pretty encouraging. However, I cannot imagine to have a windows running computer on a quad. Intel edison is another option for me: reasonably priced, small enough, and…

Cheap 1-2cm (scale) accuracy for your surveys

Image: Topcon RTK collecting survey points

High precision GPS systems are getting more known and used and RTK is already becoming a familiar acronym. This post is about the use of RTK for collecting ground control points to be used in high quality survey results, not about RTK for…

The ITG3200 started its blog on good terms.  Turns out there's no deadband, but you get a level of 8 bit quantization when reading the analog results in I2C burst mode.

NAVIO: RTK demonstration

Hey guys, we wanted to share a visual demonstration of  RTK GPS.  The demo was made with NAVIO board and Raspberry Pi running RTKLIB. Plots display how RTK GPS solution compares to a single GPS solution from the same receiver.…

New software for Reach RTK

I love both the EMLID Navio 2 autopilot add-on for Raspberry Pi and the Reach RTK GPS. But the latter was a bit hard to use initially, so this news is very welcome: they've now released a…

RTK Rover and Base Configuration Web Interface

When I first started to mess around with RTKLIB I've wanted to have a nice UI to do that, while researching it I came across a product from which already has a nice UI and I was glad to find its an open source (!!).…

Affordable new RTK GPS, designed for Pixhawk/APM

This new Indiegogo project looks very good, and at $225 Reach is about a quarter of the price of other RTK GPSs. Backed!

What is Reach and what is it for?

Reach is for applications when your standard GPS with…

Emlid Reach for placing GCP

We have been using the L1 only Reach GPS from EMLID for about 2 months. We were first attracted to the fact that it claimed that it was going to be integrated to Pixhawk and would then, via a system of magic, give us centimeter accurate geotagged images, eliminating the need for ground control forever.

While we wait for that to become a reality, we have tried out the Reach as a replacement to our normal survey…

Precision geotagging images using Emlid Reach, Canon S100, CHDK, KAP script and RTKlib – Proof of concept

We have been using a Canon S100 running CHDK and KAP script for mapping and modelling using Pix4d for a while, and thought it might be useful to share the results of some testing of the possibility of…

3DroneMapping completes PPK photogrammetry trials

3DroneMapping has been testing a PPK system for the past year to integrate into our daily workflow. The point of PPK (or Post Processing Kinematic) is not just to improve internal photogrammetric model orientations, but also is general recognised as a way of undertaking full scale surveys at the same accuracy but without having to place time consuming ground control points. 3DroneMapping setup a…
