So in India, this is the only very affordable GPS receiver I could find. It seems bizarre to me, it has a VGA port? I suppose it's used for serial communications, but there isn't any relevant information about using such GPS receivers in answers to this question. If this doesn't work with an RPi, could I interface it with an Arduino instead?

Furthermore, I plan to use the GPS for high-altitude weather balloon tracking (read 100000 feet). I don't think this GPS supports 60000+ feet tracking, so my question is, does the GPS permenantly disable itself at high altitudes? Or will it continue to work normally as soon as the GPS descends through 60000 feet?

I have checked the link to GPS and it uses regular serial port (RS232). Checking the second image, you can see 9 pins for the connector and it is regular RS232.

Regarding locking - as far as I know GPS does't lock. When there is no signal, there is no signal, and when enough satellites appear the signal gets received. The similar thing happens if you turn on GPS indoors or under water.

Check how to communicate over serial port and get some documentation about NMEA protocol (e.g. Wikipedia).
