There was a long wait - several minutes? - (at my desk near a window)
for the first data point.

Title:
  No tool exists to test SNR &TTFF on a handset

Status in the base for Ubuntu mobile products:
  New
Status in location-service package in Ubuntu:
  In Progress
Status in location-service package in Ubuntu RTM:
  New

Bug description:
  OEMs wishing to confirm that GPS is working correctly need to be able
  to observe TTFF and SNR data from a handset under test. They will
  repeat these tests in multiple locations.

  They expect to find a tool somewhere in this projects deliverables
  that they can use to do this.

  For manual verification purposes:

  * sudo apt-get update && sudo apt-get install ubuntu-location-service-tests
  * /usr/bin/uls-tests/gps_provider_test --gtest_filter=HardwareAbstractionLayerFixture.time_to_first_fix_cold_start_without_supl_benchmark_requires_hardware
  * Three trials will be run, measuring TTFF from cold start without any sort of assistance data, reporting details about visible space vehicles to the terminal.

  The timeout per trial is chosen as 15 minutes, as the theoretical cold
  start time of GPS is 12.5 minutes (see
  http://en.wikipedia.org/wiki/Time_to_first_fix).
