Model : Hi-Mate

The RTK control software Hi-Mate is software whose function is limited to the setting of the GNSS receiver. There are Windows version and Android version, and it can be installed without a license.
It is possible to set the reference station/mobile station, the NMEA message output from the serial terminal and Bluetooth, and the transfer rate.
You can also use the COM port forwarding feature to forward NMEA messages to Windows applications such as electronic flats.

The connection procedure is briefly explained on the following page.

• Connect to electronic flat panel using connection software Hi-Mate (preparation version)
• Connect to Aisan Technology INFINITY electronic flat panel
• Connect to Fukui computer TREND-FIELD

COM port forwarding function works with electronic flat boards, etc.

Conventionally, in order to use NMEA messages, it was necessary to output data from the serial port on the bottom and input it to a Windows terminal using a cable or a serial/Bluetooth converter.

In the case of a configuration using Hi-Mate, it is possible to connect directly to the N-trip service on Windows and input correction information to the GNSS receiver. NMEA messages can also be received via Bluetooth and forwarded to third-party software that uses NMEA data, such as electronic flat boards, using the COM port forwarding feature.

Base station/mobile station settings

After connecting with the GNSS receiver via Bluetooth, you can configure various settings for the base station and mobile station.
The settings can be saved as a template, so you can quickly call up and set various settings according to the mode of use.

NMEA message settings

NMEA messages can be serially output from the 5-pin port on the bottom of the GNSS receiver. The type of message to be output and the transfer rate can be set.

The NMEA messages output from the GNSS receiver’s Bluetooth can also be set in the same way.

Hi-Mate for Android

The Android version of Hi-Mate also provides similar functions. Positioning data is provided to Android apps using the pseudo-location function.

Characteristics

Hi-Target’s GNSS receivers (V100, V90plus, iRTK5x) come standard with the data collector software Hi-survey.
Hi-survey is a versatile control software for his RTK positioning with a GNSS receiver. It operates on Android 6 or higher terminals and performs total setting and observation of fixed and mobile stations. It covers all necessary functions from the collection of positioning data to surveying and route surveying.

We publish feature introductions and usage examples on our blog. You can check the list of published articles here.

Features

• Android (Ver.6 or higher) operation
• RTK/PPK/Static observation settings
• Various observation functions
• Point staking, line staking, route function
• Supports tilt survey (when using V90plus)
• DXF data, Google map can be used as background

Observation function

In addition to general 1 epoch observation and average observation (default 10 epochs), there is an automatic observation function that automatically observes at fixed time intervals and fixed distance intervals.
You can also display Google maps, DXF drawings, etc. in the background of the observation screen.

Stakeout (reverse hammering) function

Measure the coordinates imported by manual input, SIMA, CSV, etc. With the line stakeout function, center piles and width piles are staked based on defined elements (straight lines, clothoids, etc.).

A magnetic sensor built into the controller rotates the map according to the direction of the controller.

AR staking can use the camera of the controller to display the direction and distance to the staking point on the current landscape.

CAD function

You can create polylines and polygons by connecting the observed points. Created elements can be exported as CAD/GIS data such as DXF/KML.

When a CAD drawing is displayed in the background, it is possible to set it up by specifying a single point/intersection point of a line segment, a node of a polyline, etc.

Route function/cross-sectional observation

Stake out centre piles and width piles by importing definitions of centerlines, longitudinal sections, and cross sections using element input or LandXML.

You can check in real-time the difference between the defined longitudinal section/cross-section and the current altitude.

In cross-section observation, you can navigate to the cross-section that intersects the centerline you define and observe the coordinates on the cross-section.

Utilization of 3D design data

You can import TIN data such as LandXML to define surfaces. You can see in real-time the difference between the defined surface and the current altitude.

Earth volume can be calculated by comparing the current altitude and surface data formed by observing multiple points with the defined surface data.

Enhanced AR functionality. Three-dimensional data can be displayed on the landscape captured by the terminal camera.

Model : PPK Go

Characteristics

Hi-Target PPK post-processing correction software PPK Go can obtain precise and reliable drone camera position data with a significantly reduced installation of grade points (GCPs).

Analysis results are output to 2 cm accuracy by geotagging updates to text or image files and can be used directly in leading SfM software.

What are PPKs?

The general workflow for PPK (Post-Processing Kinematics) is as follows:

During flight, the UAV adds geotags to each image based on the on-board GNSS unit. At the same time, GNSS data from base stations (GNSS receivers, aerocontrollers, electronic reference points, etc.) are recorded on the ground side.

After the flight, these two GNSS data are matched by image timestamps. The image geotags are then updated to higher precision coordinates based on the PPK analysis results.

A series of steps are post-processing, so data can be collected without communication between the UAV and the reference station. Reliable positioning is possible because there is no data loss due to the communication environment or communication distance.

Workflow

Features

• Ultimate efficiency, greatly reduced work man-hours
  By using the PPK method, it is possible to significantly reduce the number of GCPs installed and perform highly accurate aerial photogrammetry. By shortening the time to correct defects in RTK-FIX, accuracy is ensured while significantly reducing field work time and costs.
• Multi-satellite system compatible
  Supports satellite systems of various countries (GPS / GLONASS / Beidou / Galileo L1 + L2 + L5, etc.), so even in environments where the signal from a single satellite system is insufficient, PPK analysis can be performed by appropriately selecting satellites. You can do. Ensures more reliable and accurate camera position coordinates.
• Electronic reference point Integrate reference station data
  PPK data can be processed without installing a GNSS base station by automatically downloading GEONET data and importing post-processed VRS data.

Trial download

Full functionality of PPK GO is available for 15 days only. If you fill in the application form, you can get manuals, catalogs, and software. Please try it.
