ShuttlePilot Portable (SPP) is carried on board the vessel being manoeuvred.
1. Calculates accurate position, heading and ROT for the vessel on which it is deployed
2. Transmits this data to the SPF on the other vessel and to any SPR in the vicinity
It combines with the ShuttlePilot Remote (SPR) and ShuttlePilot Display (SPD) to complete the installation for that vessel.
Can optionally be placed on more than one vessel who's position, heading and ROT is required for the operation (e.g. OSV's)
