Quick answers about RTK subscriptions, our GNSS devices and base stations. Can't find what you need? Contact us and we'll help.

RTK Subscriptions

What is RTK?

RTK (real-time kinematic) positioning uses correction data from a nearby reference station to improve a GNSS receiver from metre-level accuracy to centimetre-level, in real time.

What is NTRIP?

NTRIP is the protocol that delivers those RTK corrections to your receiver over the internet. You enter a server address, port, mountpoint, username and password into your receiver or app, and it connects to the correction service.

What is a CORS network?

A CORS (continuously operating reference station) network is a group of fixed GNSS base stations that broadcast correction data around the clock. GEODNET is a CORS network, and Magpie3D is an Australian reseller of GEODNET RTK subscriptions.

What do I need to use RTK?

An RTK receiver that can connect to an NTRIP correction service, an internet connection on the receiver or its controller (mobile data or a phone hotspot), and a subscription login from us.

What are the connection settings?

• Server (caster): aus.geodnet.com
• Port: 2101
• Mountpoint: AUTO
• Username and password: sent to you by email

Usernames and passwords are case-sensitive, so enter them exactly as sent. You can also use GEODNET's other regional servers if you prefer.

How soon can I start after I buy?

We usually send your login within 24 hours of purchase.

Which receivers are compatible?

Most RTK receivers that support NTRIP and RTCM 3 corrections, including survey rovers, drones and machine guidance systems. Dual- and triple-band receivers give the best results. Not sure about yours? Send us the model and we'll check.

Can I use one login on more than one device?

Each login works on one device at a time. If you need to run several devices at once, contact us about extra logins.

How accurate is it?

Typically centimetre-level with a good receiver working near a GEODNET station. Accuracy reduces gradually the further you are from the nearest station, so check the GEODNET coverage map for your area.

What datum are the corrections in?

In Australia, the AUTO mountpoint delivers positions in GDA2020. For official or cadastral work, check your results against local survey control.

Why do my heights look wrong?

RTK gives ellipsoidal heights. To get AHD heights, apply the AUSGeoid2020 model in your receiver or software.

I'm connected but not getting a fix. What should I check?

• Your device is sending its position to the server. With the AUTO mountpoint this is required; look for a "send NMEA" or "send GGA" setting.
• Username, password and mountpoint are typed exactly, including upper and lower case.
• Your receiver or controller has a working internet connection.

There's no station near me. What can I do?

Help fill the gap by hosting one. Every new station improves coverage for everyone nearby. See Host a Base Station.

Do you offer a free trial?

We can set up a short free trial on request, so you can test RTK where you work before you buy. Contact us with your location and receiver model.

How do I cancel?

Cancel any time from your account on our website, or email us. Cancelling stops the next renewal, and your login keeps working until the end of the period you've paid for.

Can I buy a fixed period that doesn't renew?

Yes. Subscriptions on the website renew automatically, but we can set up a one-off period on request. Contact us.

GEO-MEASURE

What is the GEO-MEASURE?

A rugged handheld RTK receiver that pairs with your phone. Open the free GEO-MEASURE app (iOS and Android) and start collecting centimetre-level points and lines, then export to CSV, KML, GPX or GeoJSON.

Do I need a separate RTK subscription?

Not for the first year. Every GEO-MEASURE comes with 12 months of GEODNET RTK corrections linked to that receiver. Contact us about renewal options before your 12 months is up.

How long does the battery last?

Up to 24 hours from the 49 Wh battery, with 30 W USB-C fast charging.

Can I mount it on a survey pole?

Yes. It has a standard 5/8" thread that fits survey poles and mounts. A pole isn't included.

Is it tough enough for site work?

It's rated IP67 against dust and water, drop rated to 2 m, and operates from –30°C to +65°C.

GEO-PULSE

What is the GEO-PULSE for?

Accurate positioning for vehicles, robots and fleets. It mounts on your dash or roof and gives better than 10 cm accuracy on the GEODNET network.

Do I need a separate RTK subscription?

Not for the first year. Every GEO-PULSE comes with 12 months of GEODNET RTK corrections linked to that receiver. Contact us about renewal options before your 12 months is up.

How does it connect?

Through the free GEO-PULSE app over Bluetooth or Wi-Fi. On Android it can share its position with other apps using mock location.

Does it work in tunnels and car parks?

Its built-in IMU keeps tracking your position through tunnels, car parks and tree cover, where satellite signals drop out.

Can I use it on a robot or autonomous platform?

Yes. It has native ROS2 support (Jazzy, Docker container) and a serial output with a configurable baud rate.

How is it installed and powered?

It comes with a dash mount that needs no drilling and runs from USB power, drawing less than 0.9 W.

Base Stations

What's the difference between buying a base station and hosting one with us?

• Buy: you own the GEODNET MobileCM base station, set it up through the GEODNET console and manage it yourself. Hosts can earn GEOD tokens for the coverage their station provides.
• Host with us: we supply, install and manage the station on your property, and pay you a hosting fee in Australian dollars. See Host a Base Station.

What makes a good site?

A clear view of the sky (such as a roof, shed or mast), mains power and a reliable internet connection. Sites in areas with patchy RTK coverage help the most.

How are hosts paid?

Quarterly, in Australian dollars by bank transfer. The amount depends on your station's location, uptime and network demand. Get in touch and we'll assess your site.

How much power does a base station use?

The MobileCM draws less than 2 W over USB-C.

What comes with the MobileCM?

Antenna, 9 m antenna cable, Wi-Fi antenna, USB-C to USB-A power cable, a 240 V USB wall charger, a 0.3 m threaded mounting pole and brackets.

Orders, Shipping and Billing

How can I pay?

Credit or debit card, PayTo, Google Pay or Apple Pay. We don't charge card surcharges.

Where do you ship?

Australia-wide with Australia Post. We don't ship overseas at this stage.

What is your refund policy?

• First purchase: we don't give refunds for change of mind, so check coverage with us before you buy if you're unsure.
• Renewals: if you're charged for a renewal you didn't want, contact us within 14 days of the charge for a full refund, as long as your login hasn't been used since the renewal date.
• Annual renewals: cancel between day 15 and day 28 after renewal and we'll refund what you paid less our standard monthly price, on the same condition.

This doesn't affect your rights under the Australian Consumer Law. See our Terms of Service for details.

What warranty do you offer on hardware?

12 months from the date of purchase, in addition to your rights under the Australian Consumer Law. If something's faulty, contact us with your order number and we'll sort it out.

Do I need an account?

An account lets you see your orders and manage or cancel your subscriptions online.
