Hi,
I have two newbe's questions:
1.Is it possible to get more raw data from internal GPS via LBS API? Most needed are pseudorange measurements which I want to use to recalculate the position by my application after it gets some correction data from the net.
2. Is the internal GPS module able to read RTCM correction data to recalculate the position to increase the accuracy? If yes, what methods inside LPS API are responsible for it?

Java JSR 179 API do not offer above, so maybe LBS API will do?

Thanks

Hi ,

RSG file is a header specifying resource identifier that will be created in the epoc32/include directory.
Within CARBIDE it can be found in the following path:
FirstGps/Includes/C:/Symbian/9.2/S60_3rd_FP1/Epoc32/include
This file is generated by the build process.

I had a problem here.
When I tried building the project (from FirstGps.zip) appeared an error: "FirstGps.rsg: No such or directory[/Symbian/Carbide/workspace/FirstGps/src/firstgpsappui.cpp:14]", I just started to use S60 SDK 3 FP1 (to nokia n95). Do anyone know exactly whats wrong (besides my terrible english)?
I couldn´t locate this missing file (FirstGps.rsg).

Sorry but I can't help you

You must have a problem with signing your application and there's a lot of information about the Symbian Signed procedure on the Web.

The requested Capabilitie for GPS feature is Location.

Hello

If you want to install on your device you can Sign an application for being installed on your phone only so you can have program run on your device, there's a lot of doc on the web about the SymbianSigned process, you can go to SymbianSigned.com to have more informations.

What you can not do easily is signing an applicatio for every phone but that's not what you want I think

Hi,

Quick question:

What have you had to do about signing/certifying this program?
I've been told the N95 OS wont install any programs that aren't digitally signed/certified etc.

My N95 is nearly on order, so haven't had a chance to play around with copying programs to / from any devices yet.
The program works fine on the emulator, I just need to wait 'till I have a copy of the real thing in my hands.
Good post tho...

Thanks,
Andy.

P.S. Please reply using words a complete beginner would understand.

I thinks module are hardware module

the TTechnologyType seems to describe which type of technologie is used by the hardware to locate us :
ETechnologyUnknown -> Unknown
ETechnologyTerminal -> GPS
ETechnologyNetwork -> By network ( by knowing the location of the antens where connected I think)
ETechnologyAssisted -> Assisted GPS

And TDeviceLocation seems to describe which module we use ( Internal GPS or external( bluetooth))

But I didn't played with a external GPS so ...

Thank you very much!
What's the exactly meaning of Module?Hardware or Positioning methods?And what' s relationship between Module with TTechnologyType and TDeviceLocation? I do not understand the ETechnologyTerminal
and ETechnologyAssisted meaning.If the first one stand for GPS, how to make difference internal GPS and External GPS(Blue tooth GPS)

Re: Playing with the N95 - The LBS API

marciallus — Tue, 27 Nov 2007 10:02:05 +0100

I've never try this but I think the answer is in the RPositionServer Class which has a methode GetNbModule which must tell haw many GPS module is available.
There's also the methods RPositioner ::Open (RPositionServer &aPosServer, TPositionModuleId aModuleId) which can help to choose the right module you want to use

hope that help

So this tutorial will describe a simple App, very simple App, which just get the current location of the phone and write it on the view.
