Field Portable VIS-NIR Spectroradiometer NEW

The South African National Space Agency (SANSA), a PFMA Schedule 3A public entity established under the South African National Space Agency Act, 2008, is procuring a complete field-portable spectroradiometer. The instrument will measure spectral radiance, irradiance and reflectance across the visible, near-infrared and short-wave infrared regions. It will support remote sensing field research and applications, including geological remote sensing, ground-truthing, environmental and climate research, vegetation analysis, soil characterisation, mineral exploration, forestry and canopy studies, radiometric calibration transfer, and upwelling and downwelling measurements.

The scope requires the supply, delivery, configuration and commissioning of one system. The minimum technical specification includes continuous spectral coverage from 350 nm to 2500 nm; spectral resolution of 2.8 nm FWHM at 700 nm, 8 nm FWHM at 1500 nm and 6 nm FWHM at 2100 nm; wavelength accuracy of ±0.5 nm; sampling at 2 nm or finer from 350-1000 nm and 4 nm or finer from 1000-2500 nm; fibre-optic or interchangeable fore-optic input; dark and white-reference correction; CSV or ASCII data export; and software capable of calculating reflectance and vegetation indices, including NDVI. Mandatory supplies include the spectroradiometer, a compatible fore-optic, two fibre-optic cables, two white reflectance reference panels, batteries and charger, data acquisition software, a handheld device, connection cables and adapters, a protective carrying case, calibration documentation, user and maintenance manuals, and two operator training sessions. Optional extras such as leaf clips, contact probes, cosine-corrected receptors, tripods and integrating spheres must be priced separately. Bidders must provide an OEM partner certificate or a manufacturer confirmation letter, a technical compliance catalogue with page references, and a minimum 24-month warranty.

Bidders are evaluated first on functionality, with a minimum threshold of 85 out of 100 points, and then on price (80 points) and specific goals (20 points) under the 80/20 preference system, as the estimated value is below R50 million. Specific goals cover 51% black ownership, 40% black women ownership and 51% black youth ownership, and require supporting proof such as CSD reports, CIPC registration, ID copies and BBBEE documentation. Delivery should be within two months to earn full points on that criterion. Imported equipment must be priced on a DDP (Incoterms 2020) basis with a firm, fixed price, and offers must remain valid for 120 days. The non-compulsory online briefing takes place on 20 November 2026 at 11:00, and submissions must be made through the National Treasury eTender portal by 08 December 2026 at 11:00. Late or physical submissions will not be accepted.
