Logger

A logger is a small box that contains the ZED-F9P receiver. At the top, it has an SMA connector for attaching the antenna. At the bottom, there is a 1/4 inch nut, similar to those on cameras, to use household tripods. The logger is attached to a geodetic rod with a 5/8 inch screw using an adapter (included in the kit).

To communicate with the receiver and change its settings, you can use the USB type C connector and the u-center software on your computer. To facilitate connection to the computer, a 1.8-meter USB type C - USB A cable is included.

The logger is powered by three AA-sized rechargeable batteries, which can be charged via USB. The kit includes ENELOOP PRO batteries.

To receive or transmit corrections, a Bluetooth module with a mikroBUS™ connector is inserted into the logger, designed in Clickboard™ format. See "Bluetooth Modules" for easier module selection. WiFi modules in the same format are also planned for use.

The purpose of the module is to provide communication between the logger and a smartphone, which already has internet access. For rover operation on a smartphone, it is recommended to use the SW Maps program with the built-in NTRIP client, and for the base, the recommended NTRIP server is YCServer.

The logger has a 2GB micro-SD card for recording tracks. This capacity is sufficient for approximately 2 weeks of recording. It is permissible to use micro-SD cards with capacities of up to 16GB, which can provide up to 4 months of recording. The card stores both raw measurements in the RAW Ublox format (which can be converted to RINEX format using RTKLIB) and tracks with waypoints in GPX format. The logger has a WP button for setting waypoints.

The USB type C connector serves multiple purposes. Firstly, for charging the batteries. Secondly, for receiver configuration. Thirdly, for downloading logs from the micro-SD card. And fourthly, for firmware updates of the logger. The same WP button is used to switch the USB from accessing the USB COM port of the receiver to accessing the micro-SD card.

The logger's housing features indicators for power on, GNSS signal reception, RTK correction reception, RTK fix indication, waypoint creation indication, wireless connection indication, battery discharge indicator, and USB status indicator. In short, there are many good and different indicators. However, there are only two buttons on the housing: one for turning on and off the logger, and the WP button for setting waypoints and changing the USB mode.
