QuickSurv

Rokubun’s QuickSurv logs the raw GNSS measurements from your device and
any points marked by the user. You can then send the dataset to Rokubun’s
Jason PPK service to obtain an accurate estimation of these geotags.
Sub-metric accuracies can be potentially achieved depending on the device
you are using (we recommend dual-frequency GNSS smartphones suchas Xiaomi Mi 8,
Google Pixel 4, ...) and wether or not there are nearby GNSS stations
(visit Jason web at https://jason.rokubun.cat) to check if there are any
station nearby.
Note that, to process the data with Jason, you will need to be registered.
Please go to Jason’s main page to do so.
If you are a developer, please note that this app uses the public Jason SDK
for Android that you can download and use for your own app.
We are constantly striving to provide as much valuable functionality for your
use case, please let us know how would you use the service and what features
would you add.
