Garmin 18x LVC GPS Navigator Unit

Many of these units have been purchased by me over the years, and I have not been disappointed. I have always found its accuracy and responsiveness to be above and beyond my expectations. Many years ago, I was first interested in using this unit as an APRS tracker in a vehicle. It worked for years staying on the roof of the Waterproof to a depth of 6 feet. Aside from the internal magnates and claims that it can go up to 65MPH, I can't imagine many vehicles could attain a speed at which they would peel off a roof with this thing. Additionally, it has a bolt mount hole (also weather-proof) for those who are serious about bolting it down permanently. The paint on my vehicles also does not appear to be discolored by this product. There is an internal battery or rechargeable super capacitor which retains calendar information, date/time for a period of time when it is power off to aid in resetting the device when powered back on. Upon power up, it would always acquire the signal almost immediately, always within 1 minute or less, and sometimes within a few seconds. It was portable, including working with most failing only to acquire signals from An extended power outage of months or weeks can cause the internal power to run down. It could take several minutes to recover from the power outage. There was never an issue, even in the heat of summer, winter, or car washes. Several other units were purchased for balloon-mounted APRS trackers, and again, they worked well, where other GPS units would routinely struggle to deal with 120,000 cubic feet of hot air directly overhead from a hot air balloon envelope causing massive signal refraction. A few years later, a number of the same units were ordered as a result of the 1PPS out signal to create an array of several GPS timed NTP servers for some product development uses that proved to be so precise, accurate and stable, Our NTP GPS timed servers carry a reliability rating above and beyond that of "enterprise" class servers. This is because there are no separate antenna/cable/connector components that can be compromised by moisture or weather-related factors. After the product has passed development, they are retained for full commercial use within an enterprise. It is really hard to beat this waterproof hockey puck all in one design! The GPS units have been stuck to the roof of a metal building in the snow, rain, hail, sleet, ice, heat, and sun for many years with no issues. If you need WAAS enabled GPS unit for a project, then this is the best one. I've acquired them in the past under the premise that they don't require a connection, but I've always been provided with a non-weatherproof test connector/header that I could easily remove.

Due to its highly accurate timekeeping capabilities, the GPS 18x LVC was purchased for NTP purposes I can tell you with 100 percent accuracy A pulse-like sound As a percentage The second output is available. The other GPS 18x models do not have this output. GPS 18X USB is probably the best option if you are only interested in navigation and are not concerned with precise timing. As the LVC model is an OEM specific "barewire" model, it requires a little soldering to get it configured to the way one wants to use. My alternative solution involved connecting the GPS to a circuit board that supplied power to the GPS, contained a fuse, and had LED indicators to indicate whether it was running properly A LED indicates that power has been applied, while the next LED shows when the PPS signal has been An DB-type connector can be found on the circuit board Using the serial connection to connect to My knowledge is that others have connected the PPS and data wires directly to a DB-type connector There are 9 serial ports and the power/ground wires go to a male USB-type A port Without any LEDs, this plug looks like a plug. No matter how you do it, it will work In my case, I found that the GPS draws about 60mA on its own (mine draws 75mA with the LEDs), so I was able to power it by the USB port to my laptop (which can supply 100mA without asking for more). As you can see from the review, it's a difficult task to offer a rating to the GPS unit itself, since it's so basic and has not a It will begin generating data as soon as it receives power and can see the sky. As soon as I turned it on for the first time, it managed to obtain an initial lock and output PPS signals in about 3 minutes. After that, it is able to regain the initial lock within about 5 seconds of being turned off and back on. My apartment has it atop a box next to my northeast-facing window, and it can view between 5 and 9 satellites depending on the time of day, and I am testing it inside my apartment. Even though it is designed for outdoor use, a GPS receiver cannot be used indoors because of the very weak signal strength, the 18x is quite sensitive and can receive quite good signal strength inside. There are two types of WAAS receivers WAAS/EGNOS This makes it possible to achieve From 10 to Approximately 15 minutes). The window in my computer room faces northeast, so it cannot see satellites in the southern sky where I have a WAAS satellite and EGNOS satellite in my apartment. There's a GPS 18x technical specification document available from Garmin at [for those interested in setting up the GPS receiver for either navigation or timekeeping. [] is a valuable resource as are the Garmin configuration software SNSRXCFG (Windows only, but it should work under WINE for Linux), which is located at the "Software" link at . A view from the outside In the In my case, the GPS 18x configuration was quite good, and I only changed a few settings in SNSRXCFG based on my specific needs (e. g. I'm going to increase the PPS duration from 100 ms to 200 ms, turn off the PPS if the GPS signal is lost so that I don't use bad timing information inadvertently, and so on). The circuit board was constructed and all the necessary components were soldered (about an hour or so). Then I simply followed the directions on (specifically, setting the low_latency flag with setserial, enabling the GPS 18x and GPSd software add ease to interfacing the GPS 18x with the computer. In addition to connecting the GPS device to the computer and letting NTP run for a few hours, you should run the following command A clock with an offset of 0 has been reported by p. Plus or minus 1. 000 In 003 milliseconds. The clock was synchronized to the correct time within three microseconds of its precision. It's much better than using only Internet timeservers and is thousands of times better than using time servers. The GPS receiver is well-suited for outdoor use it is small, easy to operate, accurate, etc. Precision timekeeping can be accomplished with this product, and it is quite inexpensive. Basic soldering skills are needed in order to attach the device. There is a configuration software from Garmin that simplifies changing any settings on the device itself, plus the GPS unit is compatible with GPSd and NTP as well. The GPS timekeeping option is fairly simple to use, particularly if you're looking for accurate timekeeping. A reminder that the 28th of January 2012 was a good day. Upon emailing Garmin with a few questions, they confirmed that the units will only support the L1 C/A GPS signal and the WAAS/EGNOS global positioning system An augmentation system compatible with the host system. This phone does not receive the new L2C or L5 signals, nor does it receive Galileo or GLONASS signals. By using new GPS satellites, the modernized L1C signal will also support the existing L1 C/A signal, so existing receivers like this one will continue to operate. I have updated the information as of October This receiver was mounted on the roof of the car and the serial port was connected to a laptop loaded with road navigation software. I attended a conference in Germany recently by using this receiver. While driving at 160km/h (100mph) on the German autobahn, it was held firmly in position by its magnetic base. A mounting location positioned for such a wide panorama provided a clear view of the sky essentially at The GPS satellites were tracked in the signal originating from 10 satellites The ratio of noise to signal is 481 A signal was received by the unit within a minute, and an estimated two-point uncertainty of position was reported. The speed at which you travel does not stop you from moving 5 meters. It rained heavily on the trip and the weather was poor The signal strength of the receiver did not deteriorate during this process, and it remained waterproof the whole time. Despite the receiver's particular suitability for timekeeping, it can also be used for navigation quite effectively.

The GPS receiver sits indoors on a window sill, and it acquires position in just a few.

I purchased this unit to serve as a GPS time server for a network. A DB9 serial connector was added to the end of the cable, which was plugged into a Debian machine I use a stratum one NTP server for my local network and a UNIX-based NTP server for the Internet. The unit has been running flawlessly 24 hours a day, 365 days a year. For its 1 pulse it is highly recommended As a percentage Output time for the second.
