| 3 | ## GPS |
||
| 4 | Not all GPS units are created equal! There is a [CoCOM](https://en.wikipedia.org/wiki/Coordinating_Committee_for_Multilateral_Export_Controls) Limit on commercial GPS devices. These are they should disable themselves when the altitude is over 18,000m (59,000 ft) **And** travelling over 1000 knots (510m/s, 1151mph). Some units have been found to apply the limit as an **or** rather than an **and**. Some units may need their mode switching to work at higher altitudes. Ublox modules are known to work but need a mode change to work over 12km. |
