"From my experience, to establish a position for an L1 base station using PPP, one needs to collect at least 2-3 hours of 1 second data (longer collects are better). Anything under 2 hours is useless. To get a corrected position the raw data must be…"
"Another question, will this board simultaneously log raw data so that if lock is temporarily lost that data can be post processed after a mission? Important if to be used for mapping (my application)."
"Looks promising. Would love to see a real-world example using a Pixhawk. Also, I'm wondering for aerial applications would anything be gained using your L1/L2 board instead of just the L1 board? What would adding L2 benefit? Is it just a matter of…"
"A couple questions:
1. Can these units be used to log raw gps data that could be post processed after the flight (thereby removing the need for another transmitter)?. Can one convert the raw GPS data to RINEX?
2. Using you units for both base and…"
"@Carl, right now the Seek Thermal - to the best of my knowledge - can only record to a smart phone. I'm hoping with the release of the Dev kit that it will be possible to construct an fpv device on something like a rasberry pi.
"@Ray, too bad about the connection. I got my seek over a month ago and it connected with my galaxy note 2 in a snap! Amazing device. Awesome potential for drones. Hoping Seek releases their development kit ASAP so I can work towards an FPV system."
"I've been having my trouble for weeks and tried numerous beta versions of Mission Planner. I did one last test last night, using the lastest Mission Planner Beta, and still got the same crazy numbers. After demagnitizing - viola - reasonable…"
"I just borrowed a standard (circa 1960's!) tape head, wand-style demagnitizer, from a local music shop. I'm now going to order one from ebay. They range in price from $5 -$20. I still have mixed feelings about using this device on my PIxhawk, but…"
"Ok, took a go at the demagnetization trick and got a noticeable improvement in compass calibration:
Before: -61 44 199 and 138 58 -570
After: -84 5 9 and 51 35 -70
The z values are reasonable now. Hopefully I didn't cook anything on the…"
"Finally dug uup a demagnetizer. How did you demagnetize your compass? Did you just slowly wave it over the external case? Also, it is my internal compass that is way off ( z > 500). Any idea which chip is the magnitometer? I'm also wondering if…"
"Terry, it is not the screws. The demagnetizer trick seems logical. Gonna see if I can find one of these things around town. I would love it if someone from 3DR commented on this issue. I'll let you know what happens. Maybe it doesn't matter, but I…"
"I'm struggling with this issue also. My numbers are -61 44 199 and 138 58 -570. Arg!!. Took my Pixhawk off my bird and mounted it on a board with just the external GPS to get a barebones baseline. Almost exact same numbers. Does this mean the…"
"My vote is for the Skyhunter. I also have a Slywalker, but there is very little room inside that fuselage compared to the Skyhunter. The Skyhunter has huge space, enough that a serious gimbal system can be incorporated. CHEAP. CHEAP. CHEAP. Bought…"
"Is this not a cellular based product? From reading their product page they only mention that they track via cellular networks, which does me no good. So far the only lightweight solution I can find is satellite based messaging, via a Spot Trace…"
"My vote for diy affordable mapping is a platform based on the Skyhunter. Enough room for NEX style camera with good vibration reduction and brushless gimbal and room for a couple big batteries (2 x 4000 mah). The fpv folks use this plane for some…"
"I should have clarified that I am thinking about long range Fly Away - like 10-20 km. Heck my Skyhunter with 2 x 4000mah could really leave the scene!
I am using a 3dr Radio for telemetry, but don't imagine the range on this is very far. Probably…"
