You maybe need a HAM license to
operate a wireless

First UAV flight 18-3-2003 with Movie-star

After a couple of flight my confidence increasing, the plane always return to given waypoint.Then
I could  fly the plane on a longer trip. I took the MS up to about 150m. and only looking on a
monitor for flying direction. About 1 km away I was not able to spot the plane, but have good
videofeed and could navigate very well. If I loose track I could turn on the GPS for a safe flight
home, but it was not neccesary. After 13minutes  landed MS safe on my airstrip.
It was really a very good experience, and now I think I will be able to fly with my I-Visor glasses.

It is also really nice to put  both hands in the pocket and just watching the plane circle around
a waypoint.

All in all this is a sucess.
**********************************************************************************

Since it is very expensive and difficult to buy a complete kit for GPS navigation,
I will try to build my own.

It will be based on a BASIC STAMP2 singel chip micro-controller and a
mini SSC servo drive board. This will be the first time a try a project like this
and my programming experience is just started.

The goal will be following:

1. Simpel GPS guiding. Fly  to a waypoint and stay there (circle around).
   Propotional servo deflection, depending how far off the track

2. Altitude hold.  Propotional servo deflection to hold altitude.

3. Turn it on from the transmitter on ground, and automatic if
   loosing signal (like failsafe).

4. All electronic, no relays.

5.Will need a sort of a wing leveler.  (FMA Co-Pilot)

-----------------------------------------------------------------------------------------------------------
Progress

Codes for GPS and servo movement, working ok, at least on the benk.
Since all is software, it will be some adjustment  to get correct deflections
on the servoes.  When done it will work in that particular model without
any problems, I hope

NEXT

Find a barometric pressure sensor  for altiude hold, and the electronic for
 interfaceing to the microcontroller. Hope I can manage this with serial
data.

Barometric data is working now.

A pair of IC's to make a electronic switch,  trough micro controller or
bypass for manuel control.

Working ok now.

Prototype build on a BS2 carrierboard,

Without servodriver board

Complete board with servodriver and connectors

Will come back with result after test soon.
Working to make this unit lighter.
