Skytraq PX1122R Tiny Multi-Band RTK GNSS Module Offers Centimeter Accuracy
By Lurker,
Several years ago Skytraq introduced NavSpark mini, a tiny (17x17mm) GPS module, that sold for $6. I got one and wrote a post explaining how to get started with the GPS module using GNSS viewer program.
The company contacted me again today, as they’ve now launched an even smaller module Skytraq PX1122R measuring just 16x12mm, supporting GPS, Galileo, GLONASS, and Beidou signals, as well as Real-time Kinematic (RTK) relative positioning technique that allows for 1-3cm positionin
Tutorial Basic GRASS with BASH in LInux
By Lurker,
GRASS GIS was, for a long time, something I dismissed as ‘too complex’ for my everyday geospatial operations. I formulated any number of excuses to work around the software and could not be convinced it had practical use in my daily work. It was ‘too hard to set-up’, ‘never worked well with QGIS’, and ‘made my scripting processes a nightmare’.
In this example we will:
part 1:

DJI Matrice 300 RTK drone: 55-minute flight time, Zenmuse cameras
By Lurker,
Stop me if you’ve heard this before. DJI has introduced its latest enterprise powerhouse drone, the DJI Matrice 300 RTK. We learned a lot about the drone earlier this week due to a few huge leaks of specs, features, photos, and videos. But it’s worth looking at the drone again now that it’s official – and an incredible intro video.
Also called the M300 RTK, this drone is an upgrade in every way over its predecessor, the M200 V2. That includes a very long flight time of 55 minutes, six-direc

I am much more trouble to use QGIS 2.x because there is the Metadata tab into the layer properties but I am unable to make it work. I mean, I can't see any *.xml file and w
DJI Mavic Air 2 Is a Sleeker and Longer-Flying Drone
By Lurker,
DRONE MAKER DJI announced an update to its popular Mavic Air quadcopter today. The Mavic Air 2 will cost $799 when it ships to US buyers in late May. That's the same price as the previous Mavic Air model, so the drone stays as DJI's mid-range option between its more capable Mavic 2 and its smaller, cheaper Mavic Mini.
The Mavic Air 2 is still plenty small, but the new version has put on some weight. DJI says that testing and consumer surveys suggested that most people don't mind lugging a f
