LEO PNT VERSUS GNSS

Post by dhirota »

I just spent an interesting 1.5 hours viewing a webinar on LEO PNT shown below.

For those that do not know what LEO PNT stands for:

LEO = Low Earth Orbit
PNT = Positioning, Navigation and Timing

Some people are claiming that they will have 260 satellites operational in two years, 150X more powerful L-BAND signals than GNSS. The most interesting item was a Partner's list that included HEXAGON as the only name that I related to scanning and surveying that I recognized.

Thanks Dennis for mentioning this, i will watch the webinar when i find some time.

So in 2-3 years maybe we update again our receivers?

Knowing Leica/Hexagon for the last 30 years.....have to buy new ones

The most important meeting today was with a well known un-named land surveyor that did not know what LEO PNT represented until our discussion of what it could represent. He felt that the LEO representing potential 150X of the L-BAND might allow GNSS receivers of being utilized indoors for positioning like they are currently used out doors. The rationale being that we can currently receive satellite signals in our second floor office from our Trimble R12i GNSS sensors. It would interesting to test the situation with 150X stronger signals and 3X the number of satellites or different signals from Elon Musk's 6,000 LEO satellites Starlink system.

So I decided to do a quick check and found the following

Too many new things happening now and more this summer to improve on what we already have.

People on this LaserScanningForum (LSF) need to move to different vendors who will support them in a CREATIVE HUB before their equipment versions become non-productive like it appears many are headed in that direction from the questions asked/and not asked on LSF of their work flows.
