Just over 2 years in the past I reviewed the Globalsat BR-305 and was blown away with its overall performance. Since then GPS technological innovation has moved on the whole lot and now we’ve got quite a bit increased 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 review seems for the BR-355 a GPS mouse receiver having a PS2 connector. I spent each week driving all-around New England with the USA screening the functionality of this new GPS receiver.
The Globalsat BR-355 which includes PDA interface cable retails at ?76.38 including VAT. Thanks to EasyDevices for furnishing the review article sample.
Summary
The BR-355 is often a GPS mouse design receiver made close to the SiRFstar III GPS chipset. This can be the latest and many delicate in the GPS chipsets intended precisely for pulling inside the weakest signals to supply just about the most accurate place with all the to be found info.
We’ve been screening it working with an iPAQ connector and my trusty old HP 4700 PDA. Above the period of a thirty day period or so I was only capable of use it for fairly quick journeys, so I looked forward to by making use of it as my essential navigation product for just a week lengthy excursion to New England.
Compatibility
The Globalsat BR-355 is regarded as a GPS receiver which includes an ordinary PS2 connector. There are many different PDA connectors, and these is often catered for utilising amazing adapter cables that deliver both of those strength to the PDA and facts through the GPS.
I implemented an HP iPAQ 4700 adapter cable arranged for this analyze. Discuss with your neighborhood Globalsat supplier to get an entire list of the existing suitable gadgets.
The Globalsat BR-355 overview
There just isn’t too much to mention in regards to the Globalsat BR-355 GPS. It’s a stylishly made, formed like a flying saucer. It has that futuristic start looking to it that just states “I am the latest and best…”
Strangely Globalsat haven’t any observable branding about the GPS receiver. It just has the letters GPS on it. Without a doubt you can find no Globalsat title for the system in the slightest degree.
Hidden beneath the receiver is actually a magnet and that is sturdy plenty of to help keep the GPS receiver in position regardless of how laborious the motor vehicle turns. This may be chosen outdoors the auto if demanded for the reason that cable is extensive adequate for your receiver for being put on the auto roof. Mine realistically sits firmly on a little metal speaker housing in the sprint. Checkout the picture of Henry the hedgehog under…
As with all mouse receivers it necessities to become driven to operate. The facility arrives from your cigarette lighter adapter, and never from the PDA. So will not count on for being in a position to utilize the GPS external the motor vehicle.
The GPS receiver incorporates an one red LED on it. This presents visual suggestions pertaining to the status from the GPS deal with. If ever the LED is simply not lit then there exists no electric power reaching the receiver. In the event the LED is dependable red then there is certainly no deal with. Lastly in the event the LED is flashing red then the GPS features a fix which is prepared for place reporting.
Globalsat have achieved an effective position considering the range of the LED. It’s not necessarily so vibrant that it really is distracting at nighttime time, but it surely is dazzling adequate for being viewed inside of the strongest sunlight.
Technically the BR-355 GPS receiver has the newest SiRFstarIII chipset built-in into the electronics. This have been established in exams to become the perfect and most sensitive GPS chipset available to date. It could actually pull inside a GPS satellite fix in some quite adverse problems, and it is a lot of even more cutting-edge compared to SiRFstarII chipsets as my screening proved.
As with most GPS receivers currently available the BR-355 supports WAAS or SBAS. This provides added precision at any time you have sight of one of those Differential satellites.
The in use
As talked about earlier mentioned I had been by using the Globalsat BR-355 GPS for just a couple of weeks but only managed to carry out some short assessments. I quite required to put it via its paces and give it a thorough and considerable exam. I required city canyons, tunnels, leafy overhangs, double deck bridges and a number of adverse screening environments. I discovered all this and much more on the excursion to Boston USA.
In point of fact it turned out to be one amongst the hardest assessments imaginable. When flying throughout the Atlantic and buying up the use vehicle the initial matter I at all times do is get started the 5 gps even though I’m packing the cases into the car. As we received a convertible there was even a lot less area during the trunk (sorry boot) than ordinary. By the time our baggage was packed absent the BR-355 had a powerful satellite correct.
Subsequent point was finding our lodge. I was applying TomTom Navigator computer software with the comprehensive USA Maps, and experienced definitely marked the resort so was able to decide on it and begin driving. Subsequent to 2 minutes I strike my 1st little predicament. Boston is approaching the finish of the venture described as the “Big Dig” this re-routes and submerges the key motorway passing from the town. Well GPS does not labor underground as everyone knows but happily TomTom indicated which turn to take up coming.

There have been a few breaks within the tunnels in which there was a look at from the sky for a few of hundred yards. This was way more than ample for your BR-355 to re-acquire a deal with, update my position and for the navigation program to situation the following instruction. I assumed that I’d have had major conditions navigating underground, however the sensitivity within the GPS and the programming in TomTom made it fairly painless. If truth be told it absolutely was mapping glitches that precipitated way more situations than signal reception.
Driving roughly Downtown Boston was a breeze. There was one particular celebration from the pouring rain, in the partially lined street, surrounded by skyscrapers where exactly the position was noted in the parallel street, but which was soon corrected, and could have been attributable to a map error approximately weak signals. However it absolutely was definitely a mix of the two.
Leaving Boston we did a 6 day tour of New England inside the rain. Needless to say we managed to choose the worst year for leaf colour and climate practical. We were within the USA for 8 days and it rained for 7 of them. As we left Boston we drove over the decrease deck of the double amount bridge. This was my to begin with expertise of the variety of bridge and GPS. Not surprisingly the BR-355 had a decent signal during the 2 miles or so from the bridge. That was not legitimate for my TomTom GO seven hundred which lost the resolve shortly once entering the bridge, and didn’t get it again until finally we came out into the open up once again. This quite highlighted the main difference around SiRFII and SiRFIII.
Driving in the mountains of New Hampshire and Vermont was a breeze, there have been no reception issues even when driving by “tree tunnels” inside of the rain.
Our future problems came on the previous day whenever we visited Salem. I parked within a multistory car or truck park. Now more often than not you would not hope the GPS to operate in one of those auto parks, but surprisingly the Globalsat BR-355 managed to grab a fix most of the time driving spherical the automobile park. Obviously some electronic witchcraft happening below.
Considered one of the issues that could be evident with GPS which We’ve found on some SiRFIII receivers is the fact in the event the receiver is still left driven, but there is no watch of one’s 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 definitely an individual error when Mrs Barrett knocked the power connector out of the 4 way adapter, and that i did not realise it. It took me some time to operate out what experienced transpired as being the other tools plugged to the adapter was still 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. It is surely guarded by Henry the Hedgehog.
The BR-355 can be described as WAAS receiver capable of providing a whole lot more accurate situation content for your navigation program. Even though the supplied diagnostic program includes a checkbox to help WAAS it isn’t going to 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 find out myself making an attempt to uncover fault in a very product that is apparently nearly good. The Globalsat BR-355 ticks the many bins for me. Aside from receiving a GPS signal the place GPS could not attain there’s tiny which can be executed to enhance it.
I enthused with regard to the unique BR-305 but the new BR-355 appears to be to get moved up one other amount.
If you’d like a GPS mouse receiver it’ll be very hard to uncover one that is best then the Globalsat BR-355. I am so taken with this receiver that i’m about to permanently wire it into my Toyota Supra as being the most important navigation strategy.
The only downside because of the BR-355, that’s shared by the many mouse GPS gadgets, is usually that its transferable relating to cars, but it really not moveable. What this means is that you can acquire it on holiday getaway inside of your rental automotive, but is unable to use it when hiking.
I would love to see the diagnostic applications improved this could can help you configure the GPS, and to look at diagnostics in the two NMEA and SiRF modes. The present software does not look to have been improved considering the fact that 2003.
With this in depth test the GPS was place by means of a number of the toughest issues that it could ever experience. How did it accomplish? Learn on and obtain out…
