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 &…
We recently talked about physical characteristics of our SMARTNAV-RTK GNSS and we now want to introduce the features of the application installed on the device that…Continue
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…Continue
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…
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.
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.…Continue
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…Continue
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…Continue
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…
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…
Drotek, French tech start-up is proud to release its L1 RTK GNSS ! RTK technology allows to enhance GNSS positioning and to go down to centimeter level precision.
We have seen a lot of RTK boards coming up. However we have witnessed…Continue
