Overview of the Hi-Target GPS V30 GNSS RTK System

The Hi-Target GPS V30 GNSS RTK System is a device that uses the Global Navigation Satellite System (GNSS) to determine the precise location of a point on Earth. It consists of two main components: a base station and a rover station.

The base station is a device that is fixed at a known location and broadcasts correction data to the rover station. The rover station is a device that is carried by the user and receives the correction data from the base station. The rover station then uses the correction data and its own GNSS observations to calculate its position.

The Hi-Target GPS V30 GNSS RTK System can operate in different modes depending on the application and the availability of correction data. The main modes are:

  • Static mode: This mode is used for high-precision surveying applications that require long observation time and high accuracy. In this mode, both the base station and the rover station are fixed at their locations and record their GNSS observations for post-processing.
  • Real-time kinematic (RTK) mode: This mode is used for real-time surveying applications that require short observation time and high accuracy. In this mode, the base station broadcasts correction data to the rover station in real time via radio or cellular network. The rover station then calculates its position in real time using the correction data and its own GNSS observations.
  • Post-processing kinematic (PPK) mode: This mode is used for surveying applications that require high accuracy but do not have real-time communication between the base station and the rover station. In this mode, both the base station and the rover station record their GNSS observations for post-processing.
  • Code differential GNSS (CDGNSS) mode: This mode is used for surveying applications that require moderate accuracy and do not have real-time communication between the base station and the rover station. In this mode, both the base station and the rover station receive correction data from an external source, such as a satellite-based augmentation system (SBAS) or a global correction service (Hi-RTP). The rover station then calculates its position using the correction data and its own GNSS observations.

The Hi-Target GPS V30 GNSS RTK System has many features that make it a powerful and versatile device for various applications. Some of these features are:

  • Multi-constellation GNSS engine: The device can track up to 800+ channels of satellite signals from various constellations, such as GPS, GLONASS, Galileo, BDS, QZSS, SBAS, NavIC (IRNSS), etc. This ensures reliable results in harsh environments with its unique GNSS positioning algorithm.
  • Data communication: The device has a long transmission distance and good electromagnetic compatibility with various communication protocols. It can communicate with other devices via radio (UHF or VHF), cellular network (4G or 3G), WIFI, Bluetooth, or USB. It can also connect to various CORS systems via NTRIP protocol.
  • Smart application: The device has a built-in Linux system and 8G storage. It can intelligently manage the static data and record both standard Rinex data and Hi-Target raw data simultaneously. It also has an intelligent voice assistant to guide field operations.
  • Full-frequency air antenna: The device has a stable and better noise resistance full-wave GNSS antenna that can receive signals from all frequency bands.
  • Slope method 2.0 tilt survey: The device has an innovative tilt survey function that can measure points without leveling the pole. It can automatically correct the tilt angle and direction based on gravity sensor data.

Features of the Hi-Target GPS V30 GNSS RTK System

In this section, we will introduce some of the main features of the Hi-Target GPS V30 GNSS RTK System in more detail. We will explain what they are, how they work

Multi-constellation GNSS engine

The multi-constellation GNSS engine is one of the core features of the Hi-Target GPS V30 GNSS RTK System. It is a powerful chip that can track up to 800+ channels of satellite signals from various constellations simultaneously.

The constellations that are supported by the device are:

Constellation Satellite Signals Tracked Global Correction Service (optional)
GPS L1/L2/L5/L2C Hi-RTP
GLONASS L1/L2/L3
BDS B1/B2/B3/B1C/B2a
Galileo E1/E5 AltBOC/E5a/E5b/E6
SBAS L1/L5
QZSS L1/L2/L5/L6/NavIC (IRNSS)
L5
NavIC (IRNSS) L5

The advantage of tracking multiple satellite signals is that it improves the reliability and accuracy of positioning results in different environments. For example:

  • In urban areas or areas with tall buildings or trees, some satellite signals may be blocked or reflected by obstacles. By tracking more satellite signals from different constellations, the device can increase the number of visible satellites and reduce the multipath effect.
  • In high-latitude areas or areas with poor ionospheric conditions, some satellite signals may be distorted or delayed by atmospheric interference. By tracking more satellite signals from different frequency bands, the device can mitigate the ionospheric error and improve the positioning accuracy.
  • In areas with weak or no GNSS signals, such as indoors or underground, the device can use the global correction service (Hi-RTP) to receive correction data from a network of reference stations around the world. This can enhance the positioning performance and availability in challenging environments.

The multi-constellation GNSS engine also has a unique GNSS positioning algorithm that can process and combine the satellite signals in an optimal way. It can also detect and eliminate outliers and cycle slips to ensure high-quality results.
