Leica 4G - Leica GR30 Online Help Manual

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to
provide encrypted communication and secure identification of a network web server. HTTPS connections are often used for payment
transactions on the World Wide Web and for sensitive transactions in corporate information systems.

LB2
The proprietary binary data format for streaming GPS data used by Leica.

Leica 4G

Leica proprietary RT format supporting GPS, GLONASS, Galileo and BeiDou.
Leica format
Leica proprietary RT format supporting GPS and GLONASS.
Leica format sends out reference station coordinates of the antenna phase center, not the ARP. Additionally the distance from the
marker to the antenna phase center is transmitted. The Leica format also sends the antenna type of the reference station antenna as
configured on the reference station. The rover can therefore reduce the antenna coordinate to the ARP. The reference station height
value seen on the rover can therefore be reduced to the ARP and is then displayed as entered on the reference receiver.
LLI
Loss of Lock Indicator: 4th decimal for phase measurements only, shown in RINEX format.
MDB
Leica proprietary database file format.
NMEA Log File
Leica proprietary NMEA log file. It supports logging NMEA stream messages into a file. The naming convention for NMEA log files is as
follows: ssssdddhmm.yy.nmea
NMEA file component
ssss
ddd
h
mm
yy
nmea
RefWorx 3.20 only supports logging NMEA LVM and LDM messages.
NMEA-0183
A standard established by the National Marine Electronics Association (NMEA) that defines electrical signals, data transmissions
protocol, timing, and sentence formats for communicating navigation data among marine navigation instruments.
Ntrip
Description
4 character serial number (last 4 digits) or user entered Sensor Id.
Day of the year of the first record [UT].
Hour of the day. If the file is created for the 1st hour of the day then h = a. h can have
any value from a to x. The hour indicator refers to UTC time.
Start time of NMEA file creation, given in minutes of the current hour.
The year.
File extension.
