TopNET-V viewing options
TopNET-V contains various viewing options for each added reference station in the network to provide additional information for the user.
These can all be found under the View menu in TopNET-V and include:
- Map
- Sky Plot
- Base Drift
- Base Diagram
- Latency
Map view
Accessed via View > Map.
This is the default view of all reference station locations overlaid on Bing Maps.
Sky Plot view
Accessed via View > Sky Plot.
By selecting an individual station, the user can view the Sky Plot and SNR values for that particular station.
By deselecting all stations, the SNR values for all stations for all constellations and signals will be displayed.
Base Drift view
Accessed via View > Base Drift.
By selecting an individual station, the user can view the reference station antenna drift (N, E, U) over time.
By deselecting all stations, the antenna drift for all stations will be displayed.
Base Diagram view
Accessed via View > Base Diagram.
By selecting an individual station, the user can view the total number of satellites tracked and satellites per constellation tracked over time.
By deselecting all stations, the total number of satellites tracked per station will be displayed.
Latency view
Accessed via View > Latency.
By selecting an individual station, the user can view the latency in Ethernet communication (in msec).
By deselecting all stations, Ethernet latency in msec will be displayed.
By default, TopNET-V logs all of the satellite tracking history for connected reference stations indefinitely (unless otherwise specified).
Using the Satellite Tracking History tool and these log files, the user can run reports on how well a particular station has been tracking satellites.
This can be useful if there is an issue related to the reference station receiver, antenna, or antenna cable at a given site.
The user can also plot the latency in Ethernet communication as well using these logs.
The Satellite Tracking History tool can be found by going to View > Satellite Tracking History in TopNET-V.
To run a Satellite Tracking History report for reference stations connected to TopNET-V, perform the following steps:
- Navigate to View > Satellite Tracking History.
- Go to File > Create Report.
- Select the reference stations from the list to run the satellite tracking report on.
- Specify the start and stop times for the satellite tracking report.
- Specify whether to export (and folder location of) the generated tracking statistics and Ethernet communication latencies to a *.csv file.
- Click OK.
The Satellite Tracking History report will then be generated.
The user can select any of the reference stations in the list and see the total number of satellites tracked and also satellites tracked by constellation.
Statistics showing the up time of the receiver over the generated report period are also displayed on the left side of the screen.
The main screen of the TopNET-V application reflects the current state of the network.
Once added, the reference station is displayed in the Stations panel of the screen.
The Reference station column lists each station and an icon that reflects the current status of the corresponding reference station. Its interpretation is listed in the last column, Status.
- Green icon: The station is available for RTK and Network RTK and working properly.
- Red icon: The station is available for RTK and Network RTK, but its position is not valid, or the satellite's number does not satisfy the conditions set in Preferences, or it was disabled or disconnected by an operator. The corresponding comment will be displayed.
- Left half of the icon is green: The station is available for RTK and is working properly.
- Right half of the icon is green: The station is available for Network RTK and is working properly.
- Left half of the icon is red: The station can be used for RTK, but the data are corrupted or unavailable for some reason.
- Right half of the icon is red: The station can be used for Network RTK, but the data are corrupted or unavailable for some reason.
- Dark grey icon: The station is not available for both RTK and Network RTK and is considered to be offline.
-
Triangle icons stand for non-Topcon reference stations:
- NTRIP or TCP/IP: Their colors’ meaning is similar to those of the Topcon icons.
The 4-character ID column displays the 4-character alphanumerical IDs of the stations. These IDs are used for standardized file naming.
The Group column shows the name of the group, if the station belongs to one.
The SVs (satellite vehicles) column lists information about the number of satellites received (both GPS and GLONASS).
The Last Epoch column shows the parameters of the last epoch received by the station: the GPS week number, GPS week day (Sunday = 0), and GPS time.
The Status column provides further information on the status of the station.
The Pos. Qual. column shows if the position is Precise or Standalone.
The Pos. Diff. (m) column displays the positions’ difference, or distance between the setup and received positions.
Antenna Type - shows antenna type of the receiver and that from the last message of the corresponding type, if antenna type is transmitted in RTCM.
Antenna Type Broadcast - the value of the antenna type, taken from the last message. If for some reference station this value differs from the setup value, both entries in the Station panel will be highlighted in red.
Manufacturer - the setup value of the station manufacturer.
Rec. Type Broadcast - the value of the station manufacturer, taken from the last message. If for some reference station this value differs from the setup value, both entries in the Station panel will be highlighted in red.
After a rover becomes online, its ID and information appear in the Rovers panel of the Main screen. This panel contains the following columns:
-
The Rover ID column lists the unique identification number for each rover and a solution type icon (its interpretation is listed in the Quality column):
- Red icon: The position quality is Standalone.
- Blue icon: The position quality is RTK Float.
- Green icon: The position quality is RTK Fixed.
- Yellow icon: The position quality is DGPS.
- The Mountpoint (Port #) column shows the number of the TCP/IP port(s) the rover is connected to or an NTRIP Mountpoint name if the rover uses NTRIP protocol for connection.
- The Service column displays the type of the service provided to the rover.
- The Quality column lists the solution quality, for example, type of rover position as defined in GGA messages coming from the rover.
- The Position column shows the geodetic coordinates of the rover.
- The Distance to Ref. (m) column displays a distance from a rover to its reference station.
- The SVs Sent column displays the number of satellites in the last epoch sent to the rover. The 0 + 0 value appears if no data is sent.
- The Bytes Sent column shows the total number of bytes sent to the rover.
- The IP Address column displays the IP address of the rover.
- The Ntrip User column displays the name of the corresponding user if the rover is using NTRIP for connection to TopNET-V.
- The Duration column shows the time of the rover connection to TopNET-V.
