This was done using monopropellant, Hydrazine based with six thrusters each capable of delivering 1 Newton force.

Body mounted and deployable solar panels provided 45 watts of power, with NiCd battery of 12-amp hours.

The improvements include increased on-board memory and a better measurement of the background spectra after a burst event.

These modifications led to the discovery of twelve candidate events detected up to 15 February 1995, out of a total of 993 triggers.

Measurements were made in a higher orbit for a limited period of two months during the initial phase, while the satellite apogee was at 930 km keeping the perigee same.
