6.2.3 Terminal position
In order to calculate the delay to the satellite correctly for the logon burst the Nera SatLink Terminal must
be configured with its own position.
1) Find the position of the location where installing the Nera SatLink Terminal in WGS84 coordinates
using a standard GPS.
2) Note that the Nera SatLink Terminal position is entered in degrees, minutes and 1/100 minutes.
Many GPS’es display the position in degrees, minutes, seconds, and optionally 1/100 seconds.
To convert from seconds to 1/100 minutes please use the following formula:
1/100 minutes = (seconds/60) x 100
3) Configure the latitude:
– Enter the CLI command
dvb pos lat <deg> <min> <mindec> <dir>
where
deg = degrees
min = minutes
mindec = 1/100 minutes
dir
= direction. 0 = North. 1= South.
Example:
# dvb pos lat 59 52 15 0
sets the latitude to 59°52.15'N.
4) Configure the longitude:
– Enter the CLI command
dvb pos long <deg> <min> <mindec> <dir>
where
deg = degrees
min = minutes
mindec = 1/100 minutes
dir = direction. 0 = East. 1= West.
Example:
# dvb pos long 10 29 05 0
sets the longitude to 10°29.05'E.
5) Configure the altitude:
– Enter the CLI command
dvb pos alt <height>
where
height = height in meters
