Geocache Description:


The posted coordinates are located near the Herzliya Science Center, where students develop micro satellites and send them to space for many years now with great success. The cache is hidden elsewhere.

 

Have you ever thought about how the GPS system in the phone you're holding works? 

And can you explain how GPS spoofing causes your device to think it's in a different location?

I bet you have. It's super interesting and the magic allowing this fun game.

So, unfortunately, it seems a powerful spoofer "took control" of a GPS satellite constellation including 3 satellites, which are used to triangulate the location of your device.

Below is the data your GPS device shows.

It includes the satellite geocodes and the calculated signal travel time in microseconds:

  • GCAM19V 1.23085151
  • GC8MTRE 2.24277641
  • GCAKZQM 2.93097916

Where is it pointing to? The cache will include several TBs and will be happy to accommodate more.

 

Please note the area is close to nature, in the outskirts of the city, and animals, such as snakes share it with humans. Take care when looking around.
