POWER CONSUMPTION

OK - I got to measure power consumption in the glider.

While it was still charging the device measured 432mA - With a fully charged device this should drop to around 380-400mA. The Glidertools converter measured 15mA as advertized.

This compares reasonably favorably with the high 300mA's reported for similar earlier generation PNA's reported on the PostFrontal forum.

While I was at it I compared this to power consumption of other devices.

My Becker transponder drew 390mA under very low interrogation conditions

My radio sucked 30mA with no x or TX, and a whopping 1220mA  when transmitting.

BRITE-NAV TECHNICAL SPECS

Here are the technical specs of the device. I renamed it BRITE-NAV since iGlide was already used by some software company or other. I like BRITE-NAV better anyway!

While I was at the SSA Convention this weekend I compared the Brite-Nav with the Dell Streak Android device which is a viable device if you are ok with being restriced to XCSoar - I compared devices with Ramy Yanetz and the BriteNav is clearly brighter (about 20% brighter according to my carefully calibrated eyeball) in any full sun situation but I was interested in how nicely the Streak display and interface worked. The Streak is bigger and heavier - maybe too big for some cockpits. But not by much.

Brite-Nav runs all current WinCE6.0 compatible soaring software - SeeYou Mobile (my favourite), LK8000 and XCSoar, and is compatible with all the existing third party support hardware available on line from Naviter and GliderTools.
