roughly 20% chance to drop on wave 10 and wave 25. To reach 99% chance to obtain the nav coords you'd have to make it to wave 310.

for a 90% chance to get the coordinates you'd have to get to wave 145

However, you'd expect to get at least one set of coords if you reached wave 70, 1/5 chance to get them, 5 chances to get them.

Good luck and happy hunting!
