Prognoz sattelites

Magnetic field measurements on the Prognoz satellites were carried out by IZMIRAN's Space Magnetic Research Laboratory (SMRL) in 1977-1984. Satellites had the orbits with apogees ranging from 200000 to 800000 km. (3 - 125 Re). Prognoz-6 provides important solar wind observations during ISEE-1/2 first orbits on the day side magnetopause, at a time when ISEE-3 had not yet been launched. Prognoz-7 and -9 provide observations at a later stage of the ISEE mission. It is important also to note that Prognoz-7 was launched into a high latitude orbit, and provides extensive observations of the rarely explored cusp and mantle. 

Prognoz-6

The Prognoz 6 satellite was launched 22 September 1977 into an orbit with
apogee of 200,000 km, perigee of 500 km, and an orbital period of 95 hours.
The data were obtained by an SG-70 fluxgate magnetometer provided by  
IZMIRAN's Space Magnetic Research Laboratory. The magnetometer had
a range of +/- 60 nT and an accuracy of about 0.3 nT.
It made one vector measurement every 10.24 sec.

Prognoz-7

           
The Prognoz 7 satellite was launched 30 October 1978 into an orbit with
perigee 500 km and apogee 203000 km, orbital period was 98 hours
The data were obtained by an SG-70 fluxgate magnetometer provided by  
IZMIRAN's Space Magnetic Research Laboratory. The magnetometer had
a range of +/- 60 nT and an accuracy of about 0.3 nT.
It made one vector measurement every 10.24 sec.

Prognoz-9

This directory contains magnetic field data obtained in the outer
magnetosphere and in the solar wind by Prognoz 9 between 1983/07/02
and 1984/02/10. The Prognoz 9 satellite was launched 01 June 1983 into orbit with perigee 380 km and apogee 720000 km, orbital period was 26.7 days. 
The data were obtained by an SG-70 fluxgate magnetometer provided by  
IZMIRAN's Space Magnetic Research Laboratory. The magnetometer had
a range of +/- 60 nT and an accuracy of about 0.3 nT.   It made one vector measurement every 10.24 sec.
