"We use standard resistor-based transmitter. They are not heated internally but we try to keep them warm by storing them in the battery box during the beyond line-of-sight flight phase. We once had an issue in Antarctica where a 2.4GHz transmitter…"
We are out for UAV field campaigns again. After one week of flying over sea ice of the Baltic sea in northern Finland we are now heading for Svalbard.http://blog.pfump.org
"@ Tony K We use standard LiPo batteries. They allow 1h flights at the same altitude or 5000m combined altitude in profiles. The most important thing is to not let them cool down. We put them into a 12V cooler box that is set to "heat" and keep them…"
"@Rob Flying in cold/harsh environments is something that has been done with Paparazzi for a long time. This is a video from 2009, taken over Svalbard at 78°N in (legal) 1500m altitude. The lowest temperature we measured on the ground during that…"
We spent a week on Svalbard and operated autonomous aircraft to collect atmospheric data. They were accompanied by a tethered weather balloon and an autonomous under water glider.blog.pfump.org
"They created a temporary restricted area and activate it through a NOTAMhttp://www.daec.de/uploads/media/Flugbeschraenkungsgebiet_Juist.pdf1. Location between mainland and the island of Juist2. Between GND and 300ft3. Can be activated at any time…"
John Cassano from the University of Colorado has been flying small fixed-wing UAVs in a remote camp in Antarctica. From his blog: Since it wouldn’t be possible for us to build a 3000 foot tall automatic weather station (AWS) on the Ross Ice Shelf we…
"Sam, u-blox says that it is 2Hz for flash (LEA-6H) and 5Hz for ROM, just as printed in the data sheet. The link you gave is currently not available.Chris, why did you silently modify your post from 10Hz to 5Hz (instead of correcting it)?[The LEA-6H…"
This Antarctic summer two teams flew Paparazzi driven UAS on the southernmost continent. The University of Bergen flew at the Norwegian Troll station (video) and the University of Colorado near the US McMurdo station (blog, blog). They measured…
