Interesting, I never knew #gps was so #cheap these days: https://hackaday.com/2022/01/20/ntp-serv.. This will be useful in creating the #linuxpda #project #maps and #location #system ! As #gps is #passive , it also won't reveal any #information about the #user either - unlike #gsm !
Interesting, apparently people are now looking at using a #quantum #accelerometer #imu to replace #gps https://hackaday.com/2021/11/15/vacuum-t.. This still requires occasional #groundtruth #location #updates - but it has potential. I have long been in favour of these more #passive #locators ...
