Indoor GPS, our real time Positioning System

At the Toy Fair we demonstrated our new Startkit for indoor flying with small Quadkopter or drones.
The idea is to help more people get more enthusiastic aboút the flying and help people to build good missions for a flight.
The system can be used in clubs or by individuals to train and make fun.
It could potentially be used as a professional tracking system.

One important part is the ability to track the drone on screen while it is flying. The ability always to see where the drone is in XY and also an intuitive z marker. If you build a simple mission to bang a set of balloons on screen then you need to know all 3 dimensions of your real flight - and to keep an eye on both the screen and the drone, if not listening to the associated sound. It is a bit difficult but also fun.

The starterkit has the important feature where it streams all position data on a serial port or on any TCP/IP port. The idea is to help you build your own system using the position information.

The starter kit is available in the shop - it can also be enlarged with a large drone sender for more heavy weight drones with up to 15 m distance measurements.

Our indoor GPS-system uses our own satellites which position many different sender types in operating units.
Based on a combination of radio and ultrasound they provide sharp distances to any moving or stationary unit which has a sender in the system.
The satellites provide precision up to 10 mm and can measure up to 8 m distance. Satellites are combined in scenarios of 2, 3 or more which together form a 2D or 3D position in a coordinate system. More scenarios can be combined to extend coverage.

The satellites measure all distances between moving units and the satellites. The distances are transmitted to the PC through the GT-Xconnect Radio and the PC calculates the exact position based on all measurements.

There are two satellites available for customers. They are compatible.
a) The Gamesontrack standard satellite : en.shop.gamesontrack.dk
b) The Faller Car System 3.0 satellite: www.car-system-digital.de

There are many sender types available in different moving units, LEGO Trains, Model trains from track N to track G, Faller Cars, and other units in factories etc. Please see the Webshop for standard senders available en.shop.gamesontrack.dk

We develop on demand senders for particular moving units, in toy industry as well as for professional units.

The set-up of the satellites involve
- a physical set-up and connection of power to the satellites
- a calibration step where each satellite is bound to a local XYZ position in the room.

The set-up might include further expansion with more satellites in order to cover a large space.

Satellites need some power. They are specified from 14-20 V DC, for model trains it can also be DCC power.
There are many ways to create the power:
- Use an old PC LAP-TOP charge unit. It makes normally 19 V DC. Cut the plug in the PC-end and connect the two wires (or wire and shield) to a connector in one end and 2 wires from each satellite in the other end.
- connect a 16 V Trafo (AC or DC) to the GT-Xconnect radiomaster and take out DC for satellites at the DC-connector, max 6 satellites.
- Use a DC-trafo
- Use DCC from Model trains
