Excellent points Alex, and congratulations on winning the challenge… >>1) Basically, you're right, those problems exist and, for example, Commandro >>has some tricks inside it in order to correctly respond to missing signals, >>as well as it can be run as a background service (without UI at all) with >>minimal and rare GPS interaction in order to keep saving battery.<<
That’s my approach too. There are a lot of tricks and shortcuts which need to be implemented to make consumer LBS a realistic proposition. My plan was to build all of this into an intelligent platform (see Snowball), rather than having each developer try and work it out on their own. >>2) There are also some solutions on the hardware side which we hope will be >>used in new Android phones, such as u-blog highly sensitive low-power chips >>as well as increasing the number of signal processing correlators.<< This hardware is in the pipeline, but don’t expect the fundamental limitations of GPS to be solved any time soon. Rule of thumb says - technology in experimental chips now can be in phones in something like a 3-5 year timescale. Currently we have a big drop off in performance when comparing the best dedicated GPS devices (say a TomTom) to a GPS enabled phone (say an N95). I expect this to be a problem for some time. >>3) A sophisticated Location Provider created by Google which will be able to >>integrate the last known GPS position data with Cell ID approximations (when >>the phone is out of GPS range) can also become really helpful, do you read me >>Google? << Agreed, if Google want some expert consultancy on this issue then I’m your man. ;-) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Challenge" group.
