How so? The summary of the article at the bottom of TFA, helpfully labelled "Summary", says this:
GPS antennas, located on satellites, spread across the globe, integrated into application receivers, make possible the systems that keep us on time and on track.
Sounds like parent might not be completely right, but they're certainly not "completely wrong".
- BenjiWiebe 3y agoThe antenna is not the special part. The special part is the signal processing magic that allows decoding of extremely weak signals. Also, the antennas on receivers are dramatically different then the antennas on the satellites.
- mikestew 3y agoThen I suggest GP go argue with TFA author, rather than calling out a comment as "completely wrong" when TFA summary says otherwise.
- kragen 3y agothis is correct, thank you 'they use special-purpose antennas' is as misleading an answer as 'they use electricity' or 'they use radio waves'. even the summary of the article doesn't claim the antennas are special
