I have a question regarding the SE880. I have connected the SE880 with a GE866 and it seems to work almost properly. It takes forever to get a gps signal. It gets the time rater fast but it can take forever to get a position.
What is the correct way to use the SGEE data and CGEE data?
I have not connected any memory to the GPS but the modem can be used as storage of data. Is there anyway I can use m2mlocate funcion in the modem to speed up the GPS?
Is there anyway for the GPS to tell me how good the reception of the signal is?
And finally what is this command used for AT$INJECTSTSEED
I hope someone can answer at least some of the questions
Please find below in green my comments.

you can find the SiRFInstantFix document, that shows you some technical info
about how SGEE works and what is needed.

Could you please send me your schematic
Which antenna are you using?
What is your TTFF in cold start
Could you please tell me the AT
commands, configuration that are you using? AT$GPSD… AT$GPSGPIO…?
Please note that with the usage of a
SiRF Star IV ROM 2.2 based module, so as you said all the files required are
saved into GE866 Flash as storage. However, at the moment the maximum file
available for a bundle solution with an ROM GPS module is 7days.Under warm or
cold start condition the SGEE data speed up the process of the time to first
The attached NDA and InstantFix
Agreement are necessary in order to open an account for you on our Telit Agps
Let me know if you need any further
info, I will help you in order to evaluate and use the feature.
AT$INJECTSEED is not the command for
SiRF Star IV based product, but it is for ST Teseo.
