Я нашел 2 варианта для этого сокращения, причем оба относятся к GPS:

- shorted-annular-patch

Design A High-Precision Antenna For GPS3 where a novel compact radiator, namely the shorted-annular-patch (SAP) antenna, has been introduced as a possible solution for low-multipath GPS ...

- Sim Access Profile

It enables the driver to access wirelessely NMEA-0183 standard GPS data via Bluetooth. Those Data can be used with all Smartphone or PDA. Most navigation software providers such as TomTom, WayFinder, or Navigon to name a few, sell solutions integrating high definition screen and advanced functionalities.

Thus, using the Parrot CK3500, drivers no longer need to connect their personal device to an external receiver, or invest into expensive, useless on-board equipment. Only a dashboard mounting for the PDA or Smartphone is required as additional device. Additional GPS monitoring messages such as number of satellites active or detected, geographical coordinates, speed, and heading can be displayed on the screen.

The Parrot CK3500 complements your compatible mobile phone by accessing its SIM card remotely via Bluetooth wireless technology, using the latest Bluetooth SAP protocol (Sim Access Profile). Contacts are then downloaded from a compatible mobile phone using Bluetooth SAP technology*.

The CK3500 has a separate LCD display with integrated scroll wheel that offers convenient call and message handling. Once the Parrot CK3500 has been paired with your compatible mobile phone, it's activated each time you turn on your car's ignition. The Parrot CK3500 can access the SIM card of your compatible mobile phone using Bluetooth technology.

At a time when legislation is tightening up to restrict the use of mobile phones in vehicles due to safety concerns, Parrot CK3500 benefits are not just for the sake of convenience and comfort - they are fast becoming a real necessity. The Parrot CK3500 wirelessly connects with all Bluetooth® PDAs and Smartphones on the market-compatible with all brands. The CK3500 combines comfort and safety allied with the GPS technlogy.

Учитывая, что далее речь идет о конфиденциальности данных о грузовиках, полагаю что здесь SAP = Special Access Program. Другие варианты перевода есть в МТ.

Пользователь на своем компьютере использует определенное приложение для отслеживания местоположения своих автомобилей. Данное программное обеспечение ABCD, возможно, встраивается в это SAP (или функционирует как отдельное приложение, но одновременно со стандартным используемым приложением).

Всего-лишь предположение. Из 106 расшифровок SAP на www.acronymfinder.com это мне понравилось больше всего.
