Projects General Guidance

Hey there.
I need help with gos module neo-6m
I want it to instantly give the location as soon as it is switched on. Is it possible can i do that. Co, it takes really long time to start. It is for a good project.
It is gonna be a bike crash detection. To save peoples life who went into a bike crash. Bike will automatically send the location using gsm module. To the ambulance. But i can't figure out how i can make neo-6m to take a hot start it take cold start. And 10 min after accident is like a year. And person may die if he or she is seriously injured.

Help me code for hot start. By the way i am using arduino mega 2560 r3.
I just need help with its starting time.

No.

With a decent antenna and a good view of the Sky the GPS should get a fix from power up in 40 seconds or so.

In poor reception conditions it may take some miutes to get a fix.

There are are some GPS shields that can speed up the first fix by using 'GPS assist' which in turn use a GSM module to connect to the Internet.

Bike will automatically send the location using gsm module. To the ambulance.

If this were even possible, false alarms should be an offense deserving a jail term.

Pick a different project.

If you have almanac and ephemeris data and know your approximate position and accurate time and can provide it to the GPS, it can perform a hot start. However, if you have that data, you probably don't need the GPS anyway.

Think about it though; if a GPS could actually do a hot start at any power up, why would the manufacturer torment you by being so slow? It can only do it if it has recent data.

Why not power the device up when the bike is started? Then hopefully, by the time the accident occurs, it will have a fix.

Well exactly.

some GPS modules have a puny little aspirin sized battery. they seem to lock up faster, my GEO-8M locks up in ten seconds

The batteries, and the GPS backup, is only of assistance if the GPS has been powered on in the previous 4 hours.

When the GPS is powered up for a fix and then put back into standby mode, when it wakes up again then the fix time can be a couple of seconds.

However if you monitor what happens over an extended period, there will be ocaisions when the GPS takes 25 seconds or so to get a fix, its refreshing the GPS backup which needs to be updated on a regular basis.
