GPS Chips and accuracy?

First questions is about accuracy. I have seen that the v1.8 has 3m resolution with 5 decimal place accuracy. Can this be increased by putting in waypoints on sd card with say 6 decimal place to get…Continue

"Which laser imaging device would you use to record the data? Or are you building your own LiDAR system as well???"

"Well if you can work back from, the exact track then Roberts your fathers brother. You will be able to review the track from the swathes of data that the Atto records for you or in real time via a pair of modems attached. Good luck with the bigger…"

"Dean. Thank you for the thoughtful and thorough answer. Since GPS is taking time at waypoints, I think I could post-process the data and correct the data based on the differential correction provided by CORS. This would give me as accurate as I am…"

"Oh. Does Dean have a release date on the IMU set? Ballpark that you may know? Thanks!!!! Not yet. It is still in the works."

"Here is my understanding on the GPS: With PDOP of 1.0 the lat/lon CEP (circular error of probability) is 3.0 meters. This is a measure of accuracy, NOT precision. If you use a Trimble planning software and have a current almanac and input your…"

"Thanks Gary, I know it is ambitious. That is why it is fun right? On ground scanning uses survey stations for their accuracy, planes use GPS. We contract right now with a company that does aerial survey that, because of GPS accuracy, can only get…"

"That was a bit sharp, sorry. But lifting a lidar would be a big mission, I'm sure many people are onto the case though. Legalities in the USA or in fact Europe for that matter would be a bigger mission. Don't expect anyone less than a…"

"Well you will struggle making an airframe to lift a Lidar and still come in under 2KG, the first weight restriction point in the USA. I would have thought the Lidar unit would have known exactly where and how high it was when the scan was taken and…"

Erik Baros replied to Erik Baros's discussion GPS Chips and accuracy?
"You are right about the airframe. Certainly gusting will be a factor, but what i am looking for is real precision when I create a flight plan with regards to the line the plane actually flies. This is because I am working to connect a LIDAR sensor…"

Gary Mortimer replied to Erik Baros's discussion GPS Chips and accuracy?
"Hi Erik I think other issues will come to play then, the airframe you fly better track pretty straight and true. There probably can't be much wind, or rather gusting, what happens if 15 knots of gust hits your airframe when your 10m from…"

GPS Chips and accuracy?

First questions is about accuracy. I have seen that the v1.8 has 3m resolution with 5 decimal place accuracy. Can this be increased by putting in waypoints on sd card with say 6 decimal place to get approx 10cm accuracy? What is the accuracy of the v3 IMU?Second about Chips? Could an increase in accuracy (sub-meter) be accomplished with a WAAS enabled GPS receiver? Oh, I see WAAS support is used. Then can more decimal places be used? Is PDOP measured as a tracked parameter? Does the current…See More
