Drop me an email and I will put you in contact with a guy in SA who has a fully functioning UAS which you could do a proof of concept with without having to get everything up an running yourself. Also have some leads on low cost thermal imaging equipment that will not be a pain to get into SA
- At 4:19pm on October 31, 2010, Rory Paul said…
- No do not go the route of a Predator. You are going to need something that can lug the visual and thermal imaging cameras and all the associated gear so it will have to be bigger.
I suggest that you plan this project in two phases. One with a cheap foam airframe (Cularis, Maja or similar) or maybe to learn all the problems associated with autopilot flying then a composite airframe with better capacity etc.
You are going to need to determine if this is going to be a gas or electric system. You can get better duration out of gas but it comes with vibration problems and integration issues. You also need to determine if you want the cameras to be mechanized or fixed.

R.

- I am not sure how effective a low light camera system would be at night. There was some talk a while back about using a ir illumination on the UAV (banks of ir LEDs) to try and improve the image quality.
Think less about the wing span size and more about the internals cargo bay and how easy it is to change configuration and how rugged the thing is. Landing a UAV during the day is hard enough but landing at night on a dirt road in the bush is going to be very very difficult. So you are going to need an airframe that can take plenty of punishment, can be fixed in the field and spare parts do not cost and arm and a leg. The Maja may be a good bet or something based on a Raven like airframe with a longer wingspan (improved duration) and ailerons (better handling). Look for something that can be hand launched (bungee) or catapult launched and can take a belly landing.
Regards
R.

Hi Johan,
I'm researching the almost same setup, but for neighboorhood watch. Thinking of a autopilot quadcopter with thermal video and day video. In Pretoria. The aim would be to identify criminals within a 20 minute flight window.
Thanks in advance for any assistance. Most appriciated.

John said… - Hi Johann. I have a question about Magnetometers. Can I use the Sparkfun Triple Axis Magnetometer Breakout - HMC5843
sku: SEN-09371 on the ArduPilot Mega IMU Shield if I solder the 3.3 volt jumper next to the dip switches and use the 3.3v supply from there to power the Sparkfum Magnetometer, or must I use the DIY Drones Store
HMC5843 - Triple Axis Magnetometer Rev 1.2 only. I can get the Sparkfun Magnetometer locally in South Africa, so if it will work then it will be easier to get it here.
best regards

help please
i have a the same problem with no lock on ublox 5
can you send me your config and firmware version
- At 2:22am on April 4, 2011, Johann Van Niekerk said…
Hi Bryce
Ill try help you first few questions.
1) has the Ublox worked before?
2) have you formatted Epromp before installing the latest version of APM code?
3) is the Ublox bought from DIYdrones or other source?
KInd regards PM me and we can see if we can get it working I use Ublox myself so should be able to help.

- yes, unit was puchased from diy drone ,
i have the 5v jumper set on adapter board
I get fake get long and lats and no satellites, when viewing in cli mode on AMP
Raw gps data is coming through in cli mode
When using U center 6.10 I can flash firmware to V5.00 for Jordi's tutorial and load his config file and the Satellite bars pop up full, No Lock.
If i use Chris's tutorial on version 6.00 with his config file, I don't get any satellites popping up in u center.
Binary data is streaming in u center. I have seen the satellite bars turn blue and some of the and some going's on on the other screens briefly and then it goes away.
Thats about it.....
Thanks
