Snapshot post-processing with PRIMO


Today I'd like to show what Ben, Luis, and me have been doing in our spare time and sometimes sacrifying our precious weekend hours.

Internal codename RETROFIX, it's a service running on one of our servers and processing small snapshots of data collected with PRIMO. At the moment uses about 200ms of signal and it's therefore limited in sensitivity. But surely it proofs the concept that with a coarse time tag and 128kBytes of digitized RF signal you can calculate the position and the time of a user.

If you have a PRIMO dongle just contact me and I'll send you the website address, the configuration files, and the application to grab a compatible signal: I'd love to have some feedback.

Come back soon for updates,
