Spectra SP90m
These steps connect a Spectra SP90m to the Premium Positioning correction network over NTRIP, using Survey Pro / Spectra Geospatial Origin. They assume you already have your NTRIP credentials.
Before you start
Your NTRIP username and password, from your Premium Positioning welcome email or your account on the customer portal.
Survey Pro / Spectra Geospatial Origin.
A working internet connection on the controller or phone.
A clear view of the sky at the point you are measuring.
Network settings
These are the same for every Premium Positioning customer. Only your username and password are unique to you.
Server or host: rtkpremium.xyz
Port: 2101
Mountpoint: COMMON
Protocol: NTRIP
Steps
Power on and pair the SP90m: Switch on the SP90m and your data collector. In your field software (Origin, or Survey Pro / FAST Survey) connect to the receiver via Bluetooth or Wi-Fi as usual. Pairing screens vary by app/version - use your normal connect-to-receiver workflow.
Get the receiver online: The SP90m has an internal cellular modem and Wi-Fi. Insert an activated SIM (receiver or controller) and bring up cellular data, or join a Wi-Fi network with internet. In Origin this is the 'GNSS internet source'; in Survey Pro it's the internet/data-link connection.
Open the rover survey style / data link: Origin: menu > Settings / Survey styles > select your RTK style > Edit. Survey Pro / FAST Survey: open the GNSS rover / data link configuration. Match the equivalent 'network RTK rover' area in your software.
Set the data link to Internet: Origin: select Rover data link, set Type to 'Internet connection'. Survey Pro / FAST Survey: choose the internet/NTRIP data link type (often 'Network' or 'Internet').
Open the NTRIP correction source: Origin: tap the context menu next to GNSS correction source, set Use RTX (internet) to No and Use NTRIP to Yes. Survey Pro / FAST Survey: choose NTRIP as the correction/network type.
Enter the caster host and port: Host / IP Address: rtkpremium.xyz - IP Port: 2101 - Protocol: NTRIP. In Origin these are the IP Address and IP port fields; in Survey Pro / FAST Survey the NTRIP server address and port.
Enter YOUR NTRIP username and password: In NTRIP username and NTRIP password, enter the credentials from your welcome email - unique to your account. Leave GGA/identity options at defaults unless told otherwise.
Save the connection and connect: Origin: Store the correction source, point the GNSS internet source at your live cellular/Wi-Fi connection, tap Accept, then Store the style.
Start the RTK survey: Origin: menu > Measure (choose your RTK style if prompted) > Measure points. Survey Pro / FAST Survey: start the survey / connect to the network. You'll see a 'Connecting to GNSS internet source' message.
Select the COMMON mountpoint: When the source table loads, select COMMON. (Origin can preset it: set 'Connect directly to Mountpoint' to Yes and enter COMMON to skip the prompt next time.)
Confirm corrections are streaming: The data-link icon appears on the status bar and incoming data shows. If it fails, re-check host/port/mountpoint and credentials, and that the receiver still has internet.
Wait for and verify a Fixed solution: With enough satellites and corrections, the SP90m initialises on-the-fly and the solution changes from Autonomous/Float to Fixed. Confirm the status reads Fixed (cm-level) before recording points.
If the fix will not hold
SP90m has an internal cellular modem and Wi-Fi, so corrections can run over a SIM or Wi-Fi. Field/menu names differ between Origin, Survey Pro and FAST Survey and between versions - this guide names Origin's labels precisely and describes the others generically; match the equivalent option. If it won't fix, confirm internet, the caster details, and credentials.
