"Researchers at Universidad Carlos III de Madrid (UC3M) have developed a new system which improves the ability of a GPS to determine a vehicle's position as compared to that of conventional GPS devices by up to 90 percent, and which can be installed in any vehicle at a very low cost.

The system, which…

Found a neat little plastic box at "The Container Store" for 99 cents.  Fits the UBlox LEA 6H in width and height perfectly.  May need to stuff a foam spacer on the length wise side.  Just tried it in the backyard and the GPS got a fix in about 30 seconds - the plastic cover is not adversely affecting the…

New to the ArduCopter world, so here goes.. finished my first hex build a few weeks ago, so have been working on a few cosmetic upgrades.. It's a bit silly but I like the little puck gps modules that DJI has, so decided to make and share a similar design of my own with everyone..

If you have a 3d…

Introdution

Geo-tagged aerial pictures are very useful for mosaic mapping as well as the creation of accurate 3D models from a terrain.

Michael Oborne added a great tool for injecting GPS data on the EXIF tags by using APM's telemetry log from a flight.

This tutorial was…

This is an android application that converts your mobile into a GPS tracker for your RC. But you mobile into your plane, and let it fly, it will generate for you a KML file with flying path details.  You can download it from here.…

I was just notified by a supplier of gps modules in RSA that this product has become available locally(RSA). I'm not sure how long this has been out in the rest of the world, but the following statement had my attention : NEO-6P GPS module for Precise Point Positioning....OK, what is PPP, and how accurate is it exactly. The…

The Class Diagram features of Microsoft Visual Studio provide the facility to show graphically any area of an Apm program. This is an ideal way for new users to understand how ArduPilot and ArduCopter code is designed. 

Reference

Microsoft Visual Studio provides a 100%…

Suggestions on improving flight are welcome :)

Testing the quadcopter in autonomous modes. I normally fly in Stabilize mode but today we tried switching to loiter and then tried to use the mission planner to "fly to here".

I have some work to do on getting it to fly right, yaw seems to react badly to control, yaw right and it gains…

Hello Everyone, we all know our GPS board (the one that comes with the APM1) has no battery to backup data.

This has the disadvantage to make the GPS not very precise in the first minutes after power up and that every startup is a cold startup (at least one minute to get a 3D fix).

This is because the GPS needs find the satellites without a…

It seems there are methods to increase accuracy of the GPS location to cm using a reference station network.

Real Time Kinematic (RTK) satellite navigation  is a technique used in land survey and in …

Seraphim is our sensor board for the quadcopter, it includes accelerometer, gyroscope, magnetometer, barometer, GPS and micro-SD card slot.  With the exception of the GPS unit, all of these components are a complete pain in the backside to solder properly, and there are some consequences of not…

Firstly thanks to Jason for his New Alpha code. 2.0.40. Randy for all the help and Martin who keeps supplying tea

The new control laws that he has implemented work really well. The oscillations have virtually disappeared in stabilise, and Loiter held for over 8 mins with only very slow drift, had to bring the heli back to the start point…

This new OSD was listed on the Hobbyking website today. The HobbyKing G-OSD unit is a quick and easy way to add GPS on screen information to your FPV system. With GPS Coordinates, airspeed, voltmeter and many more display functions this OSD unit will make a great addition to any FPV setup at a fraction of the cost of other GPS OSD systems currently…

I am almost sure about it, first venezuelan to use ardupilot (i hope so).

Ran my first tests in my workshop, turned everything on, including the xbee telemetry, and it worked like a charm!!!!! it is awsome....

The arduIMU works perfect, i am impresed of the sensitivity!!!!!! GPS…
