New Features -- Where Am I? Where's My Car?
The nüvi 700 series is the first to answer two common questions: "Where am I?" and "Where’s my car?"
At any time, with a single tap of the screen, drivers can display their exact latitude and longitude coordinates, the nearest address and intersection, and the closest hospitals, police stations and gas stations. And to help drivers find their car in an unfamiliar spot or vast parking lot, all nüvi 700s automatically mark the position in which they were last removed from the mount.
New Features -- Multi-Destination Routing
This lets you enter several spots into the device (day care - supermarket-cleaners - office - day care, for example) and it will plot the fastest route. And once you've found the best router, the "Route Planning" feature lets you save up to 10 different routes, Garmin touts the feature for providing, "the most efficient route for errands, deliveries and sales calls." The feature also makes this an instant essential accessory for anyone who shops garage sales (you know what we're talking about).

A trip log provides an electronic bread crumb trail of up to 10,000 points, so you can see where you've been on the map.
The super-bright, 4.3-inch (diagonal) touchscreen display gives is anti-glare for ease of viewing during the day and automatically changes its color profile for easy viewing at night or in dim light. It offers 2d or 3D perspective views.

The widescreen format gives you 70% more actual screen area than a 3.5-inch screen. Primarily this translates into a better view of the area through which you are driving. This is especially useful in showing you what parks, restaurants, ATM, gas stations, etc. are nearby, or in letting you know whether a detour is a good idea. Also, the device itself is larger, meaning controls on the screen are more widely spaced and somewhat easier to push.
First Rate Map Data
All nüvi 700s come preloaded with highly detailed City Navigator NT road maps for the entire United States, Canada, and Puerto Rico. This map database features nearly six million points of interest (POIs), including hotels, restaurants, gas stations, ATMs, and attractions. Garmin gets its map data from NAVTEQ, a world leader in premium-quality mapping.
Important note about map updates: Due to our high volume of sales, almost every Garmin portable GPS navigator sold by Amazon.com will come with the most recent map version. If you ever do need a map update, you can purchase one from Amazon.com at our Garmin Store.

Hands-Free Calling
In more and more places, it is becoming illegal to use cell phones while driving without a hands-free kit. WIth Bluetooth capability, microphone and speaker, you can match your nüvi to any bluetooth-capable phone to make hands-free mobile phone calls. Simply dial the phone number with the nüvi's touch screen keypad to make a call on a compatible phone. To answer an incoming call, just tap the screen and speak into the built-in microphone. Making and taking calls on the road has never been easier, or safer. In addition, Garmin makes it a breeze to look-up and dial numbers from your personalized phone book or even tap into your cell phone's call history log.

Integrated FM Traffic Receiver
Steer clear of traffic with an integrated FM traffic receiver designed to receive alerts from TMC Clear Channel about traffic tie-ups and road construction that might lie ahead on your route. All you have to do is simply touch the screen to view traffic details and you'll be ready to detour around any problem area. And if you end up missing a turn, or you're forced into a detour that is not relayed through the traffic receiver, the nüvi's sophisticated automatic routing will get you back on track in no time.
In most areas, TMC Clear Channel traffic broadcasts are continuous — there's no waiting for scheduled traffic news updates or random alerts. Because traffic broadcasts are received via a "silent" FM data channel, you can still listen to music or news programming on your car radio without interference from incoming FM traffic data transmissions.
A 3-month subscription to TMC Clear Channel's Total Traffic Network is included with purchase of this device. For more information on subscription fees, coverage in individual cities, and traffic data networks in the United Kingdom and Europe.

MN3310: GPS Receiver Module

MN3310: GPS Receiver Module
The Micro Modular Technologies MN3310 Global Positioning System GPS Receiver is a highly-integrated, 12-channel receiver with fast-acquisition hardware intended for OEM applications. The MN3310 is complete with integrated RF filtering, flash memory and TCXO. The single 3.3-volt power supply requires less than 150 mW total and the built-in antenna power circuit allows for a simple, direct connection to an active antenna. By incorporating the complexity of the RF signal chain into the module, the user only needs to be concerned with routing the antenna signal into the module.

The receiver tracks GPS satellites at the L1 frequency (1.575GHz) and computes position, time and velocity. The user needs only provide suitable power and a GPS signal and the MN3310 will output the navigation solution in the widely-used NMEA 0183 format. The 12-channel receiver allows all satellites in view to be tracked, providing an over-determined solution to minimize position jumps caused by individual satellite blockage. The fast-acquisition hardware design greatly reduces the time for signal acquisition when the receiver is initially powered up.

The MN3310 is machine placeable by standard surface mount equipment and is delivered in tape and reel. A metal shield is provided for RF protection and for automated nozzle pickup.

จีพีเอส (GPS:Global Positioning System)

จีพีเอส (GPS) ย่อมาจาก Global Positioning System หมายถึง ระบบบอกตำแหน่งบนพื้นผิวโลก โดยอาศัยการคำนวณพิกัด ยูทีเอ็ม (UTM) จากสัญญาณนาฬิกาที่ส่งมาจากดาวเทียมที่โคจรอยู่รอบโลก ซึ่งมีตำแหน่งที่แน่นอน ระบบนี้สามารถบอกตำแหน่ง ณ จุดที่สามารถรับสัญญาณได้ทั่วโลก โดยเครื่องรับสัญญาณจีพีเอส รุ่นใหม่ๆ จะสามารถคำนวณความเร็วและทิศทางนำมาใช้ร่วมกับโปรแกรมแผนที่ เพื่อใช้ในการนำทางได้

แนวคิดในการพัฒนาระบบจีพีเอส เริ่มต้นตั้งแต่ปี ค.ศ. 1957 เมื่อนักวิทยาศาสตร์ของสหรัฐอเมริกา นำโดย Dr. Richard B. Kershner ได้ติดตามการส่งดาวเทียมสปุตนิกของโซเวียต และพบปรากฏการณ์ดอปเปลอร์ของคลื่นวิทยุที่ส่งมาจากดาวเทียม พวกเขาพบว่าหากทราบตำแหน่งที่แน่นอนบนพื้นผิวโลก ก็สามารถระบุตำแหน่งของดาวเทียมได้จากการตรวจวัดดอปเปลอร์ และหากทราบตำแหน่งที่แน่นอนของดาวเทียม ก็สามารถระบุตำแหน่งบนพื้นโลกได้ ในทางกลับกัน

กองทัพเรือสหรัฐได้ทดลองระบบนำทางด้วยดาวเทียม ชื่อ TRANSIT เป็นครั้งแรกเมื่อ ค.ศ. 1960 ประกอบด้วยดาวเทียมจำนวน 5 ดวง ส่วนดาวเทียมที่ใช้ในระบบจีพีเอส (GPS Block-I) ส่งขึ้นทดลองเป็นครั้งแรกเมื่อ ค.ศ. 1978 เพื่อใช้ในทางการทหาร

เมื่อ ค.ศ. 1983 หลังจากเกิดเหตุการณ์โคเรียนแอร์ไลน์ เที่ยวบินที่ 007 ของเกาหลีใต้ บินพลัดหลงเข้าไปในน่านฟ้าของสหภาพโซเวียต และถูกยิงตก ผู้โดยสาร 269 คนเสียชีวิตทั้งหมด ประธานาธิบดีโรนัลด์ เรแกนได้ประกาศว่า เมื่อพัฒนาระบบจีพีเอสแล้วเสร็จ จะอนุญาตให้ประชาชนทั่วไปใช้งานได้

ดาวเทียมจีพีเอส เป็นดาวเทียมที่มีวงโคจรต่ำ ที่ระดับความสูง 11,000 ไมล์จากพื้นโลก ใช้การยืนยันตำแหน่งโดยอาศัยพิกัดจากดาวเทียม 3 หรือ 4 ดวง ดาวเทียมจะโคจรรอบโลกเป็นเวลา 12 ชั่วโมงต่อหนึ่งรอบ ที่ความเร็ว 4 กิโลเมตร/วินาที การโคจรแต่ละรอบนั้นสามารถได้เป็น 6 ระนาบๆ ละ 4 ดวง ทำมุม 55 องศา โดยทั้งระบบจะต้องมีดาวเทียม 24 ดวง หรือมากกว่า เพื่อให้สามารถยืนยันตำแหน่งได้ครอบคลุมทุกจุดบนผิวโลก ปัจจุบัน เป็นดาวเทียม GPS Block-II

ระบบบอกพิกัดด้วยดาวเทียมอื่นๆ ที่คล้ายคลึงกับระบบจีพีเอส ในปัจจุบันมีหลายระบบ ได้แก่

GLONASS (GLObal NAvigation Satellite System) เป็นระบบของรัสเซีย ที่พัฒนาเพื่อแข่งขันกับสหรัฐอเมริกา แต่ระบบนี้ยังใช้งานได้ไม่สมบูรณ์ ใช้งานได้ดีเฉพาะในรัสเซีย ยุโรป และแคนาดา
Galileo เป็นระบบที่กำลังพัฒนาโดยสหภาพยุโรป ร่วมกับจีน อิสราเอล อินเดีย โมร็อกโก ซาอุดิอาระเบีย เกาหลีใต้ และยูเครน จะแล้วเสร็จในปี พ.ศ. 2553
Beidou เป็นระบบที่กำลังพัฒนาโดยประเทศจีน โดยให้บริการเฉพาะบางพื้นที่ แต่ในอนาคตมีแผนที่จะพัฒนาโดยให้ครอบคลุมทั้วโลกโดยจะใช้ชื่อว่า COMPASS

Basic concept of GPS

A GPS receiver calculates its position by precisely timing the signals sent by the GPS satellites high above the Earth. Each satellite continually transmits messages containing the time the message was sent, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac). The receiver measures the transit time of each message and computes the distance to each satellite. Geometric trilateration is used to combine these distances with the location of the satellites to determine the receiver's location. The position is displayed, perhaps with a moving map display or latitude and longitude; elevation information may be included. Many GPS units also show derived information such as direction and speed, calculated from position changes.
It might seem three satellites are enough to solve for position, since space has three dimensions. However a very small clock error multiplied by the very large speed of light[5]—the speed at which satellite signals propagate—results in a large positional error. The receiver uses a fourth satellite to solve for x, y, z, and t which is used to correct the receiver's clock. While most GPS applications use the computed location only and effectively hide the very accurately computed time, it is used in a few specialized GPS applications such as time transfer and traffic signal timing.
Although four satellites are required for normal operation, fewer apply in special cases. If one variable is already known (for example, a ship or plane may have known elevation), a receiver can determine its position using only three satellites. Some GPS receivers may use additional clues or assumptions (such as reusing the last known altitude, dead reckoning, inertial navigation, or including information from the vehicle computer) to give a degraded position when fewer than four satellites are visible.

Global Positioning System

The Global Positioning System (GPS) is a global navigation satellite system (GNSS) developed by the United States Department of Defense and managed by the United States Air Force 50th Space Wing. It is the only fully functional GNSS in the world, can be used freely, and is often used by civilians for navigation purposes. It uses a constellation of between 24 and 32 Medium Earth Orbit satellites that transmit precise microwave signals, which allow GPS receivers to determine their current location, the time, and their velocity. Its official name is NAVSTAR GPS. Although NAVSTAR is not an acronym,[1] a few backronyms have been created for it.

Since it became fully operational in 1993, GPS has become a widely used aid to navigation worldwide, and a useful tool for map-making, land surveying, commerce, scientific uses, and hobbies such as geocaching. Also, the precise time reference is used in many applications including the scientific study of earthquakes. GPS is also a required key synchronization resource of cellular networks, such as the Qualcomm CDMA air interface used by many wireless carriers in a multitude of countries.
