The National Geoelectromagnetic Facility at Oregon State University acts as a point-of-contact for those interested in using NIMS MT systems that are maintained at the Oregon State electromagnetic instrument center. Requests for NGF instruments may be made through the web forms found on the left hand side of this page under "NGF Requests/Info -> NIMS MT system".
- Our NIMS transportable instruments available on a cost recovery basis.

Our fleet of Narod NIMS long-period MT receivers has been updated with new GNSS receivers to replace the original GPS receivers. This provides much faster satellite lock and a much larger set of satellite constellations, improving the ability to obtain and maintain precise system timing lock under challenging conditions, such as extensive tree canopy. The NIMS have also been updated by replacement of their original CF card based data logging subsystems with a new one designed and built by the NGF that uses microSD card media, allows for a much improved data file naming convention, and that operates a micro web server system interface accessible over a wireless (wifi) link that will be compatible with any wifi equipped device. A subset of the NIMS systems have also been equipped with LTE telemetry capabilities.
