iGo 8.3 have a bug

With the iGo 8.3 version in the footsteps of Europe, North America, there have been map; the most surprising is that even the use of the NAVTEQ map of the capital.

Although some people think that North American-funded plans to NAVTEQ map better funded, the author introduced before MioMap 3.2 (iGo 2006), then it is referred to vary from place to place, a matter of opinion. But the 8.3 version of the 8.0 version of NAVTEQ and TeleAtlas map POI contained in the merits of funding, will be able to see at a glance, since POI file is too small.

NAVTEQ map funding, in addition to the states POI, a AAA series of POI. Advantage is that it seems more than a number of attractions are the pros and cons are often two or three places in search of a pen to repeat. NAVTEQ map attached to the funding of POI have been less if the filter out these repeated, and I am afraid 12,000,000 than the sum of TeleAtlas POI, can only be described as pale into insignificance.

I good to be true, since the iGo 8 Design Map with POI is separate from the file, perhaps 8.0 to 2008.01 series financed POI map used to meet the 8.3 series, the use of NAVTEQ map. But with the outcome, iGo 8.3 can not read these POI.

But strange is that 2007.10 (20080311) on the contrary to the POI with the iGo 8.3 compatible. Even better, just out of the 8.0 series 2008.04 (080613) plans funded POI can be used in 8.3 years! How can this vista, the best of both worlds?

Maxtek MNT-7T : Affordable 7″ GPS System

Maxtek MNT-7T is one of the most affordable (if not the cheapest) 7″ car GPS System that I have come across. Since the most noteworthy feature is its price let’s start from that, it currently retails at $364.99 from TigerDirect. As we mentioned it features a 7″ Wide LCD TFT screen and some of its other features include, 512 MB of internal NAND Flash memory, turn-by-turn voice guidance available in multiple languages, automatic re-routing, 2D and 3D maps, audio player (MP3, WMA and WAV), photo viewer and an A/V input port that allows users to use the screen as a in-car display to watch you DVDs or play your favorite games. Finally, the Maxtek MNT-7T comes with a DVD that contains US maps. For the price it looks like a really good deal, however I wasn’t able to find any reviews of the unit.

GPS attention to the field work

GPS field work processes and Notes
network planning and time:
GPS-network planning and control related to the distribution point for the entire network of point-of-error to even the best networks can be shaped in accordance with the control points of distribution planning:

(1) control plane point of distribution:
Network-test: the best there is at least three known control point in the surveyed area outside the four quadrants, if known at 30 cents (control point) is located outside the test area, then test the outer edge of the area and are known to the point of The best distance of not more than 20km.
Linear measurement: the best there is at least three known control point in the test area and the two ends of the central, and the best there is around 30km at a known point of control.

(2) elevation control of distribution points:
Measuring network: In general, in every 10km × 10km range of domestic demand has 4 points, known as the level of control, and distributed around the test zone. If the higher elevation of accuracy, can be measured in the region elevation level of encryption to control the number of points, usually under test with a known point away from the best level of no more than 5km. Linear measurement: the best there is at least four are known to control the distribution point in the test zone at both ends and the Central. When the linear measurements larger regional district, in every 10km × 10km range at the level of domestic demand, there are known as the control point. The arrangements for the best time to avoid the midday (AM11: 00 ~ PM1: 00) observation period. Time arrangements, plans to fill in the time table and clear instructions surveyors measured leg of the mission.

points before the procedure:

Outside the industry who is responsible for this should be clearly responsible for the station staff before setting up their test site, and the switch point, the time machine, if Jiazhan were not aware of the matter, but also to the person in charge should take the initiative to understand the instructions. The following is a GPS set to be operational procedures and pay attention to:

(1) point to look for:
If it has been to the point, it should not be a problem; if it did not have been to point, and should look for points in mind, arrived at the point after point should be to confirm the number of standard rock, check correctly before setting up equipment .

(2) to set up equipment:
The first apparatus and set-centering. Usually it should be noted that: Centering in the set and level the process, not to set an antenna mounted on tripods, only to the base on the shelves. As a result of their preference for optical devices and high personal vision, but there are different-coke, so before centering should be adjusted so as to the best-Jiao, a mind seeking to avoid the occurrence of aberration. Antenna site put up after the directional antenna set point to the North (the North does not know that can be used Shizhuang lettering on the judge, the words are to the north), measuring three on the direction of the high-plate antenna ( North, Southeast and Southwest) and the corresponding number of inches, recorded. After the start, will point its antenna to receive high input instrument, and began to receive satellite data (note that the number of seconds between each data).

(3) record book in hand observation:
Hand book is to download the data and computing industry with the most important record of the information, field errors must be recorded in the books by hand to correct it, the hand-book data records request must be in the right detail. Notes:
Attention to the name, point of writing, whether or not the right; Antennas, antenna and receiver set the model, serial number records are correct;
