In a previous blog I mentioned that J Larimer J Larimer posted a way on how to get to the satellite status information that is captured by Android from the NMEA GSV messages.
I now put a little app together that visualises the satellite status in a way some GPS units do this. This is how it looks like on my OpenMoko:
On the OpenMoko this APK will run if a patch I posted on the Koolu Android Forum is applied to the Android Openmoko build as otherwise the GPS GSV NMEA messages are not parsed at all.
I do not have a G1 phone, but J Latimer's post suggested that the messages are correctly parsed on the device and that the updates are propagated through the Android stack. I would love to hear from someone if this works for you on the G1. Maybe even send a screenshot.
The APK for this app can be downloaded from here and the source is here.
