ABOUT THE TENDER
Active Hydrogen Masers provide short-to-medium-term frequency stability among all commercial and scientific atomic frequency references. This system directly bolsters India's Primary Time Scale (PTS), deep-space navigation synchronization for ISRO, and atomic time generation for the international UTC bureau (BIPM).
SCOPE OF WORK
Supply of an ultra-stable active hydrogen atomic maser, precision temperature-and-magnetic shielded environmental chamber, low phase-noise distribution amplifiers, automated cavity auto-tuning, remote telemetry interfaces, and on-site metrology commissioning.
WHO CAN APPLY?
Global manufacturers of active hydrogen masers, specialized atomic clock producers, and accredited Indian scientific technology representatives.
ELIGIBILITY REQUIREMENTS
1
Proven OEM track record of supplying active hydrogen masers to recognized National Metrology Institutes (NMIs) or space agencies (NASA, ESA, ISRO).2. Allan deviation (frequency stability) achieving documented benchmarks of better than 1.5 x 10^-13 at 1 second and 1.5 x 10^-15 at 1 day.3. Environmental chamber maintaining temperature stability within +/- 0.05 deg C.4. Comprehensive local technical support and servicing infrastructure in India.
FINANCIAL REQUIREMENTS
1
International bidding permitted in major foreign currencies (USD, EUR, CHF, JPY) or INR with customs duty exemption benefits under DSIR norms.2. Milestone disbursements upon factory inspection, laboratory installation, and 30-day continuous frequency stability proof testing.
TECHNICAL REQUIREMENTS
1
State-of-the-art hydrogen dissociator life exceeding 15 years.2. Multi-layer magnetic shielding and low phase-noise 5 MHz / 10 MHz / 100 MHz RF outputs.
DOCUMENTS REQUIRED
OEM Global Registration and Quality Certifications
Documented list of installations at leading NMIs worldwide with contact details
Allan deviation test certificates from certified international metrology labs
Detailed technical drawing and power consumption profile of the environmental chamber
Warranty, spare parts availability commitment, and Indian service agreement
