In Experiment 1, each combination of two altitudes (60 000 feet, 70 mm Hg mask pressure, 280 mm Hg anti-g suit pressure; 72 000 feet, 80 mm Hg mask pressure, 320 mm Hg anti-g suit pressure) and two anti-g suits (ATAGS and EAGLE) was tested in counterbalanced order in separate sessions.
In Experiment 2, the two anti-g suits (ATAGS and EAGLE) were tested at ground level in separate sessions using PPB and anti-g suit pressures of 80 mm Hg and 320 mm Hg, respectively.
Overall, more errors were committed in the ATAGS than in the EAGLE suit at 72 000 feet (mean percentage errors - ATAGS: control = 7.4 [+ or -] 0.4, 60 000 feet = 9.0 [+ or -] 1.9, 72 000 feet = 20.8 [+ or -] 2.0; EAGLE: control = 7.8 [+ or -] 0.6, 60 000 feet = 10.5 [+ or -] 1.6, 72 000 feet = 16.1 [+ or -] 1.4).
More errors were committed in the ATAGS than in the EAGLE anti-g suit at 72 000 feet, but this result should be treated with caution in view of the fact that a suit difference did not emerge in the RT analysis.
DRDO achieved yet another technological breakthrough by successfully conducting the proof firing of Armament system for 155 mm x 52 calibre Advanced Towed Artillery Gun System (ATAGS) during the technical trials conducted recently at Proof & Experimental Establishment (PXE), Balasore.
ATAGS is fully indigenous towed artillery gun system project undertaken in mission mode by DRDO as a part of artillery modernisation programme of Indian Army.
ATAGS is configured with all electric drive to ensure maintenance free and reliable operation over a longer period of time.
The development trajectory of ATAGS aims at establishing indigenous critical defence manufacturing technologies with the active participation of Ordnance Factories, DPSUs and Private industries including Bharat Forge Limited, Tata Power Strategic Engineering Division and Mahindra Defence Naval System to meet the aspiration of Make in India initiative in defence sector.
