L1 (PT-code), GPS frequency L1 (C/A code) and GALILEO at the frequency E1. The navigation receiver ML8088s is designed on the basis of the latest specialized chipset STA8088FG, a part of the family so-called "systems-on-a-chip" STA8088. The receivers have a high sensitivity, low energy consumption, and a short start time. - Page 4 The Receiver operation is performed with the help of special ST GNSS NMEA commands. This document describes a new sample evaluation board for the receiver ML8088s. The description of the old model evaluation board is available in the document "Evaluation board ML8088s RE v1_0.pdf".

Page 12: Navia Glonass + Gps Application
The receiver embedded software is in standard factory release unless otherwise specified. The application Navia GLONASS + GPS has an embedded system of pop-up prompts and an extensive Support section. The prompts are displayed when the cursor is pointed at an area which can be manipulated by the user. -
Page 13: The Board Activation
(see Fig. 4). Application Configuration The Navia viewer application should be run after the board has been connected to the computer. This is necessary because after the application has been started, it checks all the available serial ports of the user computer. - Page 14 Evaluation Board of ML8088s Receiver Operating Manual 2.0 Fig. 8.
