[OSM-talk] SBAS - (EGNOS / WAAS)

[Andy Robinson]

Out of interest, who has SBAS (Satellite Based Augmentation Systems) ie WAAS
/EGNOS turned on and active on their handheld (or other) GPS units when
logging?

With Europe's EGNOS setup due to commence "Initial Operations" from INMARSAT
3 F2 (AOR-E) (Garmin ID 33) in the next few days I suspect it will get some
publicity. Obviously the testbed has been running some time now but clearly
the platform is moving to a more reliable phase beyond testing and I guess
we should all be using it if we have an SBAS enabled GPS receiver.

In the UK I can generally only pick up satellite ID 33 on my Legend, I
assume that most others in Europe are picking up both 33 and 44? (44 being
INMARSAT 3 F1 (IOR))

Any feedback on whether the activation of SBAS on your GPS is actually
improving the traces you make?

Also, is anyone actually using DGPS (ie differential GPS using 2 receivers)
for logging?

As I say, just for interest, although partly aimed at considering best
practice and urban mapping issues.

Cheers,

Andy
