GRI 4970
Identification
Open-source references do identify GRI 4970 as the north-western CHAYKA / RSDN-5 chain, but the publicly described sites for that chain do not line up with the supplied point. A local Inta reference describes the Inta station as the lead station in an RSDN-5 three-station network, while public chain lists place other GRI 4970 sites at Tumanny and Pankratyeva Island. On that basis, the point at 60.3107N, 65.9664E cannot be confidently confirmed as a documented GRI 4970 site from open sources and may reflect a mis-tagged or different record.

Documented chain
Official RIRT history describes CHAYKA as a Russian long-wave terrestrial radionavigation system analogous to Loran-C. RIRT states that the European CHAYKA chain entered service in 1969, a mobile CHAYKA variant was fielded in 1975, the Northern chain entered service in 1996, and stationary CHAYKA sites have since been modernized while new chains are being formed around the ISKVO «Scorpion» architecture. This supports the broader relevance of CHAYKA, but it does not verify this exact coordinate. ([rirt.ru](https://rirt.ru/aboutmain/istoriya-instituta/))
Location-specific evidence
I did not find an authoritative public government, military, or corporate source that ties the supplied coordinate itself to a named CHAYKA transmitter, mast field, garrison, or active radio-navigation installation. The sources reviewed instead point GRI 4970 to other published locations, especially Inta and the far-northern RSDN-5 sites. Accordingly, infrastructure details, present operating status, and any unit attribution for this exact point are not publicly confirmed.

Assessment
Best open-source judgment: this record should be treated as an unconfirmed or ambiguous association with CHAYKA GRI 4970 rather than a verified site identification. The defensible briefing is therefore limited to system-level context: CHAYKA remains part of Russia’s terrestrial radionavigation legacy and has been subject to modernization, but the supplied coordinate cannot be linked with confidence to a documented GRI 4970 node using currently available open sources.
