If your Android tablet or head unit keeps losing its place on the map, the fix is a small USB puck that pulls in satellite signals on its own. The short answer: the GlobalSat BU-353N is the one to buy for most people, because it pairs a roof-mount magnet and a 75-channel receiver with Windows, Mac, Android, and Linux support. The two other options are worth a look for very specific setups, and this guide explains exactly which one fits your dash.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
These are simple accessories, but they are not plug-and-play on every device — the app and USB host support matter as much as the hardware. Below you get the plain-English version of what each receiver does, who it suits, and where it falls short, all in one place for your android gps usb setup.
Our Picks at a Glance
How To Choose The Best Android GPS USB Receiver
A USB GPS receiver is the part that actually listens to satellites and hands your device a position, so it does not have to guess from cell towers. The buying decision is less about raw hardware than about whether your specific Android device will talk to the receiver at all. Get the compatibility right and the rest is easy.
Check USB Host support before anything else
Your Android tablet or head unit must support “USB Host,” which is the feature that lets it power and read a plugged-in device like a receiver. Without it, the receiver gets power but your apps never see the data. One of the picks here spells out that requirement plainly: it needs USB Host plus the “PL2303 GPSInfo” app to function on Android. Check your device’s spec sheet for USB Host before you buy anything.
Understand the app layer
A receiver feeds raw satellite data to your device, and an app turns that into a usable location. The BU-353N and BU-353N5 both note that Android is supported with an app required, so budget a minute to install a GPS utility or navigation app that accepts an external receiver. On Windows, some of these need a third-party tool to appear as a standard “GPS Sensor,” which is normal for this class of device.
Look at satellite systems and channels
More channels and more satellite constellations mean the receiver can hold onto more signals at once, which helps in cities and under tree cover. A 75-channel receiver tracks many satellites simultaneously. The BU-353N5 goes further by listing GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS support, so it can draw on several satellite networks instead of one.
Plan where the puck sits
The receiver needs a clear view of the sky, and how you mount it matters more than its size. A built-in roof-mount magnet lets you stick the puck to a metal roof or dash frame so it stays put on rough roads. Suction-cup hardware is also common in this category, and one of the picks ships with a suction cup in the box.

In‑Depth Reviews
1. GlobalSat BU-353N USB GPS Receiver
Our pick — 4.0+★ from 90+ verified ratings; the strongest balance of quality and price.
The magnetic puck that turns any Android tablet into a real satellite navigator.
Start with the number that decides the job: 75 channels. That is the count of satellite signals the receiver can work with at once, and a higher count means it holds a lock more steadily when buildings or trees block part of the sky. It is a genuine all-in-view tracker, so it listens to every satellite it can see rather than switching between them. For a tablet glued to your dash, that steadiness is the whole point.
The second reason this takes the top spot is that it fits more vehicles and more devices than the other two picks. It is listed for Windows, Mac, Android, and Linux, and it carries a built-in roof-mount magnet so you can plant it on metal and forget it. It also ships with a suction cup in the box, giving you a second mounting option. At 60 inches long by 2 inches wide by 0.5 inches high, the cable runs from the roof to a dash port without dangling across the windshield.
What owners value is the price-to-capability balance — a fair spend for a receiver that just works on common Windows setups. The honest wrinkle is reliability: it comes in for mixed feedback, with some units holding a fix for years and others going functionally dead. Treat it as a small accessory that may need replacing down the road rather than a lifetime part. Buy it if you want Windows, Mac, Android, and Linux support plus a built-in magnetic mount in one receiver.
Where It Earns Its Spot
- 75-channel all-in-view tracking keeps a lock steadier in built-up areas.
- Works across Windows, Mac, Android, and Linux — one receiver, many devices.
- Built-in roof-mount magnet plus a suction cup in the box for flexible placement.
The Reasonable Objection
- Reliability draws mixed feedback; a small share of units stop working.
- Android needs an app installed before the receiver does anything.
Buy it if: you want the easiest magnetic mount and the widest device compatibility for a car or truck tablet.
Pass if: you need a receiver that fits a pocket or a cramped laptop port — this one runs 60 inches long.
2. GlobalSat ND-105C Micro USB GPS Receiver
A thumbnail-sized receiver for the laptop bag and the cramped second screen.
Size is the story here. This receiver measures 1.2 inches long, 0.18 inches wide, and 0.61 inches high, so it disappears into a pocket or a crowded USB hub. Put that next to the BU-353N at 60 inches long and 2 inches wide and the difference is the whole use case: this one travels, the other one stays in the car. It suits a desk tablet, a small head unit, or any setup where a 60-inch cable would get in the way.
Inside, the MediaTek chipset is rated at a tracking sensitivity of -165 dBm, which is a measure of how faint a satellite signal it can still read — the lower below zero the number goes, the weaker the signal it can pull in. It also carries a built-in backup battery and a red status LED that tells you when it has a fix. Buyers report it locks onto satellites within 20 seconds, and many like that it works with various non-iOS devices. The compact size and the connectivity are the two things it does best.
Set your expectations around setup, though. It needs your Android device to have USB Host support and the “PL2303 GPSInfo” app before it will function, and the compatibility record is mixed — some laptops pair with it perfectly and some units do not work at all. A few note durability as a concern over time. If your device meets the requirements, though, it is a genuinely pocketable way to get a satellite fix. This is a niche tool for people who read the requirements list first.
Signal performance: The -165 dBm tracking sensitivity and the fast time to first fix (TTFF — how long it takes to lock its first position) make it quicker to settle than its tiny body suggests.
What to know before you plug it in: It only works with Android devices that support USB Host and run the PL2303 GPSInfo app, and it comes with a micro USB to USB adapter cable for laptops.
The right call for: desk tablets, compact head units, and laptop setups where a long cable would get in the way.
Think twice if: your device lacks USB Host support — this receiver will not function without it.
3. GlobalSat BU-353N5 USB GNSS Receiver
Six satellite networks in one puck — for when a single constellation is not enough.
Here is where this one pulls ahead of the BU-353N above: it supports GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS, while the BU-353N lists GPS only. Those extra systems mean it can draw on more satellites from more networks at once, which is what you want in a city canyon or under heavy tree cover. The 75-channel receiver is the same all-in-view design, so it tracks everything it can see. If a dependable fix in dense cover matters more than price, this is the stronger receiver.
The setup story is the opposite of fussy. Owners mention it is easy to set up and installs automatically when plugged in, and it is praised for holding a good GPS fix. That combination — automatic install plus a steady lock — is exactly what you want from a receiver you plug in and leave alone. It carries the same built-in roof-mount magnet and ships with a suction cup, so mounting is just as simple as on the BU-353N.
The caveat is track record. This is a newer version with a smaller base of experience behind it, so the long-term reliability picture is less settled than on the BU-353N. It is also listed as Android-supported with an app required, so the same USB Host check applies. For a driver who wants the best chance of a clean lock in difficult terrain, this is the pick; for a first receiver on a tight budget, the GPS-only BU-353N is the safer bet.
Why It Pulls Ahead
- Works across GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS — far more satellite networks than the plain GPS pick.
- Installs automatically when plugged in, so setup is quick.
- Holds a good GPS fix and mounts with a built-in roof magnet or a suction cup.
The Honest Trade-Off
- A newer model with a thinner track record than the BU-353N.
- Android still needs an app and USB Host support to function.
Reach for it when: you drive tight streets, tree-lined roads, or anywhere one satellite network would drop out.
Look elsewhere if: you want the most-proven reliability on a narrow budget over the widest satellite coverage.
Understanding the Specs
Channels and satellite systems
A channel is a slot the receiver dedicates to one satellite signal, so 75 channels means it can listen to many at once and hold a fix when part of the sky is blocked. Satellite systems are separate networks in orbit — GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS — and a receiver that supports more of them has more satellites to choose from. That breadth is what separates the BU-353N5 from the GPS-only BU-353N.
Tracking sensitivity and TTFF
Tracking sensitivity, written in dBm, measures how faint a signal the receiver can still read; the ND-105C is rated at -165 dBm, which is a weak-signal figure suited to a car cabin. TTFF stands for Time To First Fix — how long it takes to lock onto its first position after power-up. A short TTFF means the map settles faster when you switch the device on.
USB Host and the app layer
USB Host is the feature that lets an Android device power and read a plugged-in receiver. Without it, no receiver works regardless of specs. On top of that, Android typically needs an app — the ND-105C names the PL2303 GPSInfo app — to translate the satellite data into a location your navigation software can use.
NMEA output and mounting
NMEA0183 is a standard format for satellite data that navigation software across platforms understands; the ND-105C supports NMEA0183 V4.0. Mounting choices — roof-mount magnets and suction cups — decide whether the puck keeps a clear view of the sky. A magnet holds the receiver to metal, while a suction cup lets you reposition it on glass or the dash.

Final Thoughts: The Verdict
For most people, the android gps usb winner is the GlobalSat BU-353N because it combines a 75-channel receiver, a built-in roof-mount magnet, and support for Windows, Mac, Android, and Linux in one unit. If multi-constellation accuracy in difficult terrain is your priority, step up to the BU-353N5 and its GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS support. And if you need something that disappears into a laptop bag or a cramped setup, the ND-105C at 1.2 inches long is the one to reach for. Whichever you choose, confirm USB Host support first — that single check decides whether the receiver does anything at all.
