Sure, you can also get instantaneous speed and direction.

Good. Having worked on about a dozen GPS receiver projects using different chipsets, here is a very short list of caveats however:
1. Precision. While once "warmed-up", a GPS receiver delivers good precision, in a "push-to-fix" mode, i.e. intermittent operation, things may not always look as good. Fixes may be tens of metres off. Depending on the object you are tracking this could give you false indications. Now ten meters are negligible when tracking an aircraft in flight, but with eg a person, 10m make the difference between a report of "object is stationary" and "object is moving". The solution usually involves leaving the receiver powered for a bit longer, taking a sequence of fixes and averaging them, eliminating outliers etc. This however takes time and battery power.
2. Time. Don't assume your receiver will always be able to get a fix. Tough situations include indoors, under heavy tree cover, in a narrow city street lined with tall buildings, or just somebody's hand covering the antenna. In these cases and unless you program it otherwise, the receiver will just keep searching for satellite signals, forever. Searching (acquisition) is generally expensive in terms of power consumption. Remember that a GPS receiver either works acceptably, or doesn't work at all. When unable to get a position fix, as far as the receiver is concerned its location may be anywhere in the universe, so it will report "Dunno". To spare you this sort of frustration, program the tracker to report something like "No fix, but the last one was [lat/lon/alt] at 10:46PM..." when it can't see enough satellites after trying for a (predefined) time.
3. Battery power must be carefully budgeted: No answer and no report at all is even worse than "Dunno"
Antenna choice and placement, interference issues (eg with GSM!) are also important points.
The above is not meant to discourage you, rather to help set and frame your expectations, as well as to plan ahead and find workarounds for less-than-perfect practical situations.
To be more helpful it would obviously help to know more about your project: what are you planning to track, for how long, is the tracker unattended; size and preferred mounting location etc. Feel free to PM me.
