Just above 2 many years back I reviewed the Globalsat BR-305 and was blown away with its overall performance. Since then GPS technological innovation has moved on the lot and now we’ve got a lot of more vulnerable GPS receivers.
Sometime ago Globalsat introduced the clearly been given BT-338 SiRF III bluetooth chinese gps, they have now adopted that up with two SiRF III mouse receivers. This evaluation seems within the BR-355 a GPS mouse receiver using a PS2 connector. I spent each week driving approximately New England with the USA screening the effectiveness of the new GPS receiver.
The Globalsat BR-355 which include PDA interface cable retails at ?76.38 together with VAT. Thanks to EasyDevices for furnishing the review sample.
Overview
The BR-355 is usually a GPS mouse design receiver made close to the SiRFstar III GPS chipset. Here is the latest and many delicate with the GPS chipsets made precisely for pulling inside the weakest signals to supply the best correct position aided by the around information.
We have been screening it utilizing an iPAQ connector and my trusty aged HP 4700 PDA. More than the interval of the month or so I had been only able to use it for fairly brief journeys, so I seemed forward to by using it as my principal navigation procedure for your week long journey to New England.
Compatibility
The Globalsat BR-355 really is a GPS receiver that has a conventional PS2 connector. There are many different PDA connectors, and these can be catered for employing specific adapter cables that make available the two electrical power to your PDA and info from the GPS.
I employed an HP iPAQ 4700 adapter cable set for this assessment. Seek the advice of your native Globalsat provider for just a finish record for the current compatible devices.
The Globalsat BR-355 evaluation
There isn’t really a lot to mention regarding the Globalsat BR-355 GPS. It is a stylishly created, shaped like a flying saucer. It has that futuristic appearance to it that just says “I am the newest and finest…”
Strangely Globalsat don’t have any seen branding on the GPS receiver. It just has the letters GPS on it. Indeed there is certainly no Globalsat identify within the product in any respect.
Invisible underneath the receiver is a really magnet that is certainly formidable sufficient to maintain the GPS receiver in place no matter how challenging the automobile turns. This can be applied external the car if needed because the cable is extended more than enough to the receiver to become placed on the car roof. Mine truly sits firmly on the minor metal speaker housing about the dash. Checkout the image of Henry the hedgehog down below…
Just like all mouse receivers it needs for being run to work. The ability happens on the cigarette lighter adapter, and not in the PDA. So don’t hope to become in the position to make use of the GPS outdoors the auto.
The GPS receiver provides a single red LED on it. This features visible opinions concerning the position for the GPS resolve. In case the LED is not lit then there’s no electrical power reaching the receiver. If the LED is stable red then you can find no resolve. At long last if the LED is flashing red then the GPS contains a correct and is particularly all set for situation reporting.
Globalsat have accomplished a good occupation along with the collection of the LED. It’s not so dazzling that it’s always distracting during the night time, nevertheless it is vivid more than enough to get observed while in the strongest sunlight.
Technically the BR-355 GPS receiver has the latest SiRFstarIII chipset built-in into your electronics. This has long been confirmed in tests to be the most efficient and many delicate GPS chipset attainable up to now. It could pull in the GPS satellite repair in certain really adverse illnesses, and is particularly so much a good deal more superior as opposed to SiRFstarII chipsets as my screening proved.
Just like most GPS receivers available today the BR-355 supports WAAS or SBAS. This offers increased precision should you have sight of 1 of such Differential satellites.
The in use
As stated previously mentioned I’d been employing the Globalsat BR-355 GPS for the very few weeks but only managed to accomplish some small checks. I very needed to set it due to its paces and provides it a thorough and broad check. I desired urban canyons, tunnels, leafy overhangs, double deck bridges and a variety of adverse testing environments. I discovered all this and a lot more on a journey to Boston USA.
The fact is that it turned out to get one in all the toughest exams conceivable. Right after flying across the Atlantic and choosing up the hire car or truck the 1st problem I nearly always do is begin the process of the 5 inch gps even while I am packing the cases to the auto. As we obtained a convertible there was even fewer home inside trunk (sorry boot) than typical. Through the time our luggage was packed away the BR-355 experienced a robust satellite fix.
Upcoming idea was locating our hotel. I used to be by means of TomTom Navigator software programs along with the whole USA Maps, and had previously marked the lodge so was capable of decide upon it and begin driving. Upon 2 minutes I strike my foremost very little issue. Boston is approaching the end of the mission named the “Big Dig” this re-routes and submerges the primary motorway passing through the metropolis. Perfectly GPS doesn’t perform underground as everyone knows but fortunately TomTom indicated which switch to acquire next.

There have been some breaks from the tunnels where exactly there was a see of your sky for the couple of of hundred yards. This was more and more than more than enough to the BR-355 to re-acquire a repair, update my placement and for that navigation application to dilemma another instruction. I thought that I’d personally have experienced severe problems navigating underground, even so the sensitivity of this GPS and then the programming in TomTom crafted it moderately painless. In reality it had been mapping issues that triggered greater troubles than sign reception.
Driving near Downtown Boston was a breeze. There was just one occasion inside pouring rain, inside of a partially covered highway, surrounded by skyscrapers exactly where the placement was documented inside of a parallel highway, but that was quickly corrected, and might have been caused by a map error as much as weak indicators. Despite the fact that it was quite possibly a combination of both equally.
Leaving Boston we did a six day tour of New England inside rain. However we managed to select the worst yr for leaf color and temperatures feasible. We have been from the USA for eight times and it rained for seven of them. As we still left Boston we drove on the decreased deck of a double level bridge. This was my number one practical knowledge of the model of bridge and GPS. Not remarkably the BR-355 experienced a high quality sign through the 2 miles or so in the bridge. That was not valid for my TomTom GO seven hundred which lost the correct soon upon entering the bridge, and did not get it back again until eventually we came out in to the open up yet again. This truly highlighted the real difference relating to SiRFII and SiRFIII.
Driving through the mountains of New Hampshire and Vermont was a breeze, there were no reception difficulties even if driving because of “tree tunnels” around the rain.
Our next difficulties arrived within the very last day when we visited Salem. I parked in a very multistory automotive park. Now commonly you would not anticipate the GPS to operate in a single of such car or truck parks, but astonishingly the Globalsat BR-355 managed to seize a repair more often than not driving round the car or truck park. Naturally some digital witchcraft occurring listed here.
One in all the problems which could be evident with GPS which I have looked at on some SiRFIII receivers is that often if your receiver is left run, but there’s no look at from the sky then once the GPS can see indicators once more it doesn’t receive a deal with. This did not arise using the BR-355 every single night we had been in Boston the motor vehicle was parked in an underground storage and continuously had a fast correct as soon as it arrived out into the city streets again. This was not so by using a pair of other SiRF III GPS devices we were testing.
The reality is the one complication I have encountered is often an individual error when Mrs Barrett knocked the power connector away from the 4 way adapter, and that i didn’t realise it. It took me some time to operate out what had took place because the other gear plugged in to the adapter was however working.
Back household We have my PDA mounted to the dash utilizing a Brodit Mount. This offers a solid system for my navigation process. The GPS by itself is firmly hooked up to some metal speaker cover by it truly is magnetic base. This is certainly surely guarded by Henry the Hedgehog.
The BR-355 can be described as WAAS receiver able to furnishing alot more exact placement knowledge on your navigation computer software. Even if the supplied diagnostic software has a checkbox to allow WAAS it does not seem to be to truly get it done. The one way We’ve been capable to help WAAS on other products is by using SiRF Demo, and you also will need to link into a Computer to to that.
Conclusions
Once yet again I notice myself making an attempt to uncover fault in the machine that appears to be just about most suitable. The Globalsat BR-355 ticks each of the containers for me. Apart from acquiring a GPS sign where GPS simply cannot arrive at you can find small that may be accomplished to improve it.
I enthused with regards to the first BR-305 although the new BR-355 looks to have moved up yet another stage.
If you want a GPS mouse receiver it will likely be problematic to discover one that is better then the Globalsat BR-355. I’m so taken using this type of receiver that i am gonna once and for all wire it into my Toyota Supra because the key navigation program.
The only real drawback while using the BR-355, that is shared by each of the mouse GPS products, is it is always transferable amongst vehicles, nevertheless it not transportable. This implies you can just take it on holiday as part of your rental automobile, but are not able to use it when hiking.
I’d personally want to see the diagnostic program improved this should assist you to configure the GPS, also to watch diagnostics in each NMEA and SiRF modes. The current application doesn’t appear to obtain been improved because 2003.
During this broad exam the GPS was put through some of the hardest disorders that it could ever endure. How did it complete? Go through on and pick out…
What’s inside the box
The Globalsat BR-355 comes without any connectors apart from the PS2 connector. As a result you are going to require a PS2 adapter suited on your PDA.
There is certainly also a CD with some utilities on it to diagnose any conditions you will have together with your setup.
Globalsat offer a large collection of adapter cables for PDAs. These offer strength towards GPS and therefore the PDA simultaneously, they also deliver the data from your GPS on the PDA too.

You certainly will also will need some kind of mount to position your PDA within the vehicle. This is often not equipped as half of your package, even so the retailer that you buy the gps with mp3 from should preferably have a good quality selection of mounts and holders to choose from.
