1 UPrecise Introduction
1.1 Description of UPrecise
UPrecise is a GNSS evaluation software developed by Unicore. It aims to help you conveniently do operations on the receivers with graphical real-time monitoring and playback function.
Using this software, you can interact with receivers by serial ports or Internet and see the status information. After connecting the receivers, UPrecise can automatically identify the baud rates and type of the receivers, and display the specific message configurations and parsed sentences.
1.2 Functions of UPrecise
You can see section 2 for the detailed functions and here just introduces the basic information. Interacting with the receivers
UPrecise can display the raw data in real time or playback, and provides a command input box for real-time interaction with the receivers.
Showing constellations The window “Constellation” can display a general distribution of the visible satellites in real time or playback.
Showing satellite tracking status The window “Tracking Status” displays the change of C/N0 and tracking status in real time or playback, which varies according to the window size (normal size or maximized size).
Showing the positioning information The window “Map” shows the positioning information including the positioning point and the trajectory drawn in real time or playback on the loaded map in the language you select (Baidu map or Google map). The function is particularly suitable for viewing the trajectory of the running cars.
UC-00-S39 EN R2.0
UPrecise Introduction

Showing the attitude information The window “Attitude” displays the information of positioning and attitude, which enables you to know the receivers’ attitude intuitively.
Showing discrete degrees The window “Trajectory” shows the longitude and latitude of the positioning point, as well as the horizontal discrete degree in real time or playback. When receiving static signals, it enables you to view the degree in different scales.
Parsing messages The window “Message” dynamically displays the parsed NMEA and other messages according to the type of the receivers.
Configuring receivers The window “Receiver Configurations” enables you to query and configure the parameters of the receivers according to its type, so that you can interact with the receivers more intelligently.
Upgrading receivers UPrecise supports the firmware upgrade of the receivers from Unicore.
Replaying With the “replay” function, the software uses the saved data to show the parsed messages and draw visual graphics. Except the data saving and command interaction, other functions can work as same as those in real time.
Supporting interference detection, RTCM monitoring and TTFF testing
UPrecise provides the tools to detect the interference at 1575.42 MHz, 1227.60 MHz and 1176.45 MHz as well as monitor the RTCM data and test TTFF.

2 Using UPrecise
To use UPrecise, you can install the software with the installation package, or you can use the green package directly. The former situation can avoid file corruption, and in the latter situation, you just need to place all the files such as DLL, EXE and LIB into the same folder.
If your antivirus software identifies UPrecise as suspicious, choose to trust it.
After installation or copying, double click the icon or UPrecise.exe to run the software and its primary layout is shown in Figure 2-1.

2.3.3 Constellation
After successful connections, UPrecise analyzes the received data and displays all satellites parsed by the receivers in the “Constellation” window (See Figure 2-8).
The window shows a general distribution of the visible satellites in real time or playback. Currently, it supports displaying seven navigation systems: GPS, BDS, GLONASS, Galileo, QZSS, SBAS and NavIC, which can be selected or deselected by clicking the national flags. The system a satellite affiliates with can be distinguished by the flag icon.
For the products with dual antennas, you can choose to display the information received from the master antenna (by default) or the slave antenna through the drop-down box.
Figure 2-8 Constellation
To see the visible satellites, you must enable at least one of the following messages according to the protocols supported by the receivers.
GSV(GSVH)5; SATVISA; SATVIS2A; SATELLITE; SATSINFO.

2.3.4 Tracking Status
This window “Tracking Status” displays the changes and tracking status of the visible satellites and C/N0 value in real time or playback. It can display multiple frequencies of multiple systems including GPS, BDS, GLONASS, Galileo, QZSS, SBAS and NavIC. With the normal size, this window just displays the satellite numbers of one system and C/N0 values at different frequencies, and displays the average C/N0 value of the current system and the average of the top four C/N0 values. You can switch between different systems by clicking the flag icons (See Figure 2-9). When the window is maximized, it can display maximum four satellite systems and their C/N0 values at different frequencies at the same time, as well as the average C/N0 values and the average of the top four C/N0 values (see Figure 2-10).

The figure above shows the real-time interference strength at the three frequencies.
The three figures below record the variation of the interference strength from the start of the detection to the current state. The abscissa is the detection times and the ordinate is the interference strength with a range of 0 to 255.
The larger the interference is, the more effect it has on the positioning.
