  1. Aerial mapping with Pteryx UAV motorway construction site length 20km (40km round trip) A short report of a custom mission flown by Pteryx UAV. Normally you are expected to use pre-programmed missions flying over a square area using rotary mission selector mounted on the fuselage. This time we demonstrate a case when the client has supplied a list of 200 fixed coordinates. Around 30 of them were used for defining round-trip route hoping to map the motorway construction site in Poland. We have used a light compact camera and unusual payload of batteries that allowed more than 1.5h of autonomy (it could have been more but was estimated to be already an overkill). We have used only 50minutes of endurance in presence of 20km/h head-wind which is close to operational limit for photomappping. The takeoff and landing was in manual RC mode because we wanted to have a nice landing video, there was 2min of manual control during the whole flight. As a recovery a parachute landing is possible, plus the system is designed as having multiple failsafe conditions. We were lucky to find a parallel road so we were able to maintain visual contact during the flight, which otherwise was 40% over forests, 50% over fields mixed with trees and 10% over public roads. Flight altitude 200m above terrain level. Air traffic control was aware of our activity. pteryx.eu

The pricing is sub-2KUSD.
  4. Note precise track following and functional mission simulator. It helps a lot to confirm on the flying field that everything is set up OK. In the worst case, it will fly to customizable rethome zone and automatically return to takeoff point but the flight would be wasted. The video shows benefits of mission planning using mission simulator on the PC connected directly to the autopilot built in the RC plane. You are sure what photos will be triggered and in what order the waypoints will be visited. Using moderate flight altitude of 200m (always obey the local air trafic rules!) you can obtain the list of GPS coordinates from flight logs stored in the autopilot, using dedicated software. Matching the photos with GPS positions using free software gives accurately positioned images. http://vimeo.com/5832423 The photos are made in tight airspace, unachievable with other means except full scale helicopters, baloons and cranes... Path following precision, in particular, is limited to GPS accuracy. Unimaginable to fly such patterns with sensitive RC plane or full scale aviation.
  5. Hi, I would like to announce the availability of a new ready-to-fly UAV based on EasyStar. Sold assembled, tuned and flight tested (incl motor, servos, ESC, installed autopilot, wings not glued). The user needs RC TX, 6ch RX (PCM or anything with failsafe is a must for UAV), Lipo3S around 2000mAh, own video system or camera. 450g of payload or ballast INCLUDING the camera. You can connect to 2 servo triggers dangling in the nose section. The autopilot is placed under the wing (the safest place). For advanced users, waypoint scripting is possible using USB console. Log download and parsing software (export to GoogleEarth) is available. Made in EU, worldwide availability. The whole idea was to leave the front bay for the user: you can put there your lipos, RVOSD, digital camera etc. It has 2 independent trigger channels, logging, USB connectivity with console. The sales are starting soon, you can watch the first official movies. Site photo mission High altitude, pinpoint autonomous landing Long range Repetitive Flying a 3D pattern Bad weather EasyUAV uses 6DOF IMU autopilot and 5Hz GPS plus barometric altitude sensor. This is a genuine design, not sharing any software nor hardware with anything else. easyuav-manual Features and more important documentation below: flexipilot-advantage flexipilot-features flexipilot-installation flexipilot-navigation flexipilot-software flexipilot-triggers flexipilot-weather It can land autonomously following full landing approach, but due to wing loading and weak static thrust of the small pusher propellers, the takeoff must be manual.

  6. wow, copper antenna. is this is a plain copper plate? how does it wears with time?
  7. SMA is 2 times smaller than F. (SMA is MUCH more expensive, and maybe patented somehow).
  8. Hi, I have several GP patch antennas scaled to 1170MHz (1.2GHz) band. They are roughly twice the size of 2.4GHz antennas and must be custom made because 1.2GHz is not very common on the consumer market. Now when tin covered steel plates used to cover roofs that I had in stock are depleted, I want to buy a new one. What is the best choice of materials among of what I can get in construction shops: - 1mm alu plate and 0.5mm oxidized steel plate for small box plate - both made of tin covered steel - both alu - both oxidized steel - both copper! copper as a good conductor, may bend easily but let's suppose we will handle it gently, unfortunately it can oxidize easily. from what I understand from discussion on painting the antennas, silver covered copper should be second next after pure gold plate ;-) But maybe try copper plate sprayed with automobile paint containing alu dust? I have no means of measuring it so I am not 'experimenting', I want your advice. Secondly, what should we use as spacers? I used to use pine wood with 15min epoxy. Using nylon screws is out for 2.4GHz because of the hole size (might affect parameters?). So maybe glued nylon spacers. BTW why ppl tend to use nylon in some professional grade antennas?
