name: SBAS
full_form: Space Based Augmentation System
context: Nominal accuracy requirement verifies the accuracy of A-GANSS position estimate in ideal conditions. The primarily aim of the test is to ensure good accuracy for a position estimate when satellite signal conditions allow it. This test case verifies the performance of the first position estimate. In this requirement 6 satellites are generated for the terminal. If SBAS is to be tested one additional satellite shall be generated. AWGN channel model is used. The number of simulated satellites for each constellation is as defined in table 5.2-2. Table 5.2-1: Test parameters If QZSS is supported, one of the GPS satellites will be replaced by a QZSS satellite with respective signal support. If SBAS is supported, the SBAS satellite with the highest elevation will be added to the scenario. Table 5.2-2: Satellite allocation
description: The Space Based Augmentation System (SBAS) is a technology that enhances the accuracy and reliability of satellite navigation systems, such as GPS. It uses additional satellites to provide corrections to the navigation signals, improving the overall performance of the system.
explanation: The text explicitly states that SBAS 'enhances the accuracy and reliability of satellite navigation systems' and 'uses additional satellites to provide corrections to the navigation signals'. This clearly identifies it as a technology directly related to satellite navigation.
