One Button Survey (OBS) prepare crowdfunding launch
Epoc Unmanned inc. creators of the OBS UAV survey system announces that we continue to evolve and are now actively testing dual frequency receivers; here is our latest fully functional dual frequency prototype
We’ve received many great emails and questions over the past few weeks; one of the most common questions is ‘What’s wrong with single frequency? Ublox/NVS/Emlid/Drotek etc. are all getting cm accuracy!”. There is a very important reason why very few single frequency survey systems are sold today:
Spot the observation time we tested in the first column! Under ideal conditions single frequency systems (Ublox in the chart above) require 10 minutes or more to reach the same level of accuracy dual frequency systems achieve in 3 minutes or less. Under less than ideal conditions single frequency receivers can require much, much more time to produce acceptable accuracy.
An average UAV survey (gravel pit, construction site etc.) will require 15-20 ground control points to achieve repeatable cm accuracy – plus 3-5 check shots for quality control/validation. The difference between single and dual frequency systems is more than 3.5 hours of labour!
We received strong customer feedback that reducing labour by more than 300% would quickly repay the increased cost of dual frequency receivers – and after many hours of field testing, we have to agree. Single frequency can be accurate, but under real-world conditions, it is slow, inconsistent and often frustrating to work with.
Look for our Kickstarter announcement on November 28, 2016, when we bring easy surveying to the masses with no subscriptions, no network connections and no target toting hassle. For only $3900 USD you can place unlimited ground control and check shots forevermore not to mention the endless other applications for an easy to use surveying unit.
See our video for OBS here, note that OBS is now controlled by Bluetooth and the video is slightly out of date.
