Hello, I am looking to purchase a now-discontinued NovAtel GPS receiver, specifically the GPStation-6 GNSS Ionospheric Scintillation and TEC Monitor (GISTM) Receiver. <https://www.novatel.com/products/scintillation-tec-monitor/gpstation-6/> I have not been able to get a direct response from NovAtel if they might have any remaining units. Any leads for this specific receiver would be appreciated. Thanks, Dan
