UHP-1000 SATELLITE ROUTER

INSTALLATION AND OPERATION MANUAL, V. 2.5

(SW VERSION 2.5.X)

 Calculate expected elevation and azimuth (corrected accordingly to magnetic declination). Such

calculations can be performed with UHP Calculation Tool available on the Documentation CD or can be

downloaded from the Web.

 Direct the antenna toward the satellite. When installing the angle of elevation please take into account

offset angle of parabolic antenna (specified in the description) or use an elevation scale of antenna.

 Access the information about actual signal level of satellite router with any of methods described below.

 Start moving antenna slowly in limited angle of elevation and azimuth. The value of the demodulator

input level increases when antenna receives signal from any satellite. Signal peak means proper pointing

to the satellite.

 After finding the peak of this signal by adjusting the azimuth and elevation, it is necessary to provide

demodulator some time to search for and capture the carrier from the Hub. Search for the carrier with

symbol rate of 250 ksps in the band of 3000 kHz (slowest case) may take about 30 seconds. If

demodulator is unable to lock on a carrier for a long time it may mean that antenna is pointed to a wrong

satellite and it’s necessary to continue moving the antenna in search for another satellite.

 When demodulator locks on the carrier the router begin to show actual C/N level, the maximum of which

is necessary to achieve by fine tuning the azimuth and elevation of the antenna.

 Once the satellite is found, it is necessary to tune the polarization angle in accordance with the

procedures applicable to this satellite. Afterwards, the terminal may get a permission to start

transmission. (see Section 2.7).

 You can reduce demodulator’s scanning time by adjusting the frequency shift and narrowing the search

range as outlined in the Section 2.5.5.

2.14.1 Pointing with HTTP assistance

“Pointing” window of the router displays information about the quality of signal reception (Figure 23) and

simplifies the procedure of an antenna pointing.

Figure 23 HTTP Information about the quality of signal reception

The information about demodulator’s quality of reception is displayed in the graphical and textual form. Search

phase is also shown below when demodulator is unlocked. Please allow demodulator to pass all search cycle

before changing azimuth and/or elevation angle. When demodulator locks on the carrier textual and graphical

information about level C/N will replace the information about search phase. Proceed with fine-tuning of antenna

azimuth and elevation until a maximum of C/N level is achieved.

2.14.2 Pointing via management console

Pointing assistance via console is activated by “demodulator antenna” command. When such mode is active the

console will display a string with actual information which is updated two times per second.

If there is no reception of the carrier yet, the string looks like this:

When the demodulator is locked on the carrier the string looks like this:
