a, Reliance BIG TV India : footprint in South Asia -KU band- defined by the satellite operator
Measat 3 at 91.5°E - South Asian footprint : results of measurements of the town Lučenec / central Slovakia
geographical location : Latitude: 48.33° _ Longitude: 19.72°
measurement results are derived from the 3.7 m diameter antenna
ground without obstacles in the horizon length to 1000 m
date of measurement : 29.8.2010
elevation angle : 3.3°
Measat 3 at 91.5°E : South Asian footprint in the KU band
coverage area with the possibility of reception,depending on antenna diameter from 180 to 800+ cm , with the highly unstable
and continuously oscillating signal level in the geographical locations with elevation angle less than 10 degrees :
Middle East / D=180-250+ cm - West Asia+East Europe / D=300-360+ cm - Central Europe / D=360-500+ cm
Central Africa / D=600-800+ cm

--- defining the status of reception ---
12 515 > 12 684 > 12 724 H : lock the carriers is unstable and non-cyclical oscillates in one second intervals in a wide
range of amplitudes of the quality from MER=5 dB (what is the level of detection for FEC protocol 5/6 ) to MER= 8+dB
which is the fair gain margin of more than MER=2 dB ! Even when the level of radiated power EIRP continuously oscillates
in the measuring point, measuring results over a period of 120 min. confirmed that the average level of gain on DVB-S
carriers BIG TV was about 1.5-2 dB dB lower than the packet carriers SUN Direct.On the basis that the period of
measurement and aggregation of data was only 120 minutes, I can not objectively say that the quality of the reception
packets from a broadcaster Sun Direct is higher by an average of MER=1.5-2 dB,compared with Reliance BIG TV .This
qualitative status I identified only in a defined period of time .
