Overview
GlobalSat built this receiver to hand raw satellite positioning data to a connected computer or Android device over USB, drawing on multiple satellite networks at once for a stronger and faster location fix than a single-system unit.
Pulling from several satellite networks rather than GPS alone helps it lock a position faster and hold it in more difficult reception spots. It supplies location data only, so mapping and navigation software has to run on the connected computer or phone. Android use depends on an app that can read the connection, which is not included.
Who it's for
Someone building a mapping, tracking, or navigation setup on a laptop or Android tablet that has no GPS hardware of its own is the target buyer here. Anyone wanting a screen-based, ready-to-drive navigation device needs a different product.
Pros and cons
- Tracks four satellite networks for a faster fix
- Magnetic mount attaches to a car roof
- Works across Windows, Mac, Linux, and Android
- Backup power retains data between power cycles
- No mapping or navigation software included
- Android use depends on a separate compatible app
- No display of its own to show a position
Performance notes
Position data streams over the USB connection using the NMEA 0183 protocol, a text-based format that navigation and mapping software reads directly. Combining several satellite networks rather than one lets the receiver keep more satellites in view at once, shortening the time to a first fix and steadying the signal near buildings or trees. A magnetic base holds it flat against a metal roof so the antenna keeps a clear view of the sky while driving.

Frequently asked questions
Does the GlobalSat BU-353N5 need regular maintenance?
No, there are no moving parts or batteries to service; wiping the housing and keeping the antenna face clear of debris is the extent of its upkeep.
Can the BU-353N5 be moved between a car and a laptop?
Yes, the magnetic mount lifts off the roof and the USB connector plugs into any compatible computer or Android device, so it moves between setups without tools.
Does the BU-353N5 work with Windows navigation software?
Yes, it outputs standard NMEA 0183 data that Windows mapping and GIS software reads directly, provided the software supports GN sentences.
Is the BU-353N5 a standalone GPS unit?
No, it has no screen or mapping software; it supplies location data to a connected computer or Android device that runs the navigation software.
