Controlled reception pattern antennas or CRPA is a term related to GPS anti-jam technology that is used for defense. CRPA is a system of antenna elements that generally functions by exploiting spatial diversity. There are several CRPA simulators that you can purchase in order to test the precision of the CRPA to ensure its accuracy. However, to make sure that the results will stay consistent, it is imperative that you conduct maintenance on a regular basis. Here are a few areas that you may want to cover when maintaining your CRPA simulator.

Preventive Maintenance

You should make sure that the CRPA simulator is properly maintained at all times. Improving its maintainability will guarantee that the machine will be able to maneuver both the hardware and software environments where you will be utilizing the GNSS equipment.

Perfective Maintenance

With perfective maintenance, you will be able to properly address all the functional changes that the CRPA simulator requires in order to meet the industry requirements. Any performance improvements done on the CRPAs will also fall on the perfective maintenance category.

Corrective Maintenance

CRPA simulators still have a margin of error at times despite their quality. When this happens, it is essential that you identify those errors and have them corrected before they can cause any major issues with your GPS system. Check the polarizability of your simulator and other factors that may affect its performance to ensure that it will function properly.

Proper maintenance of your CRPA simulator is essential to make sure that the machine will work properly at all times. It is highly advisable to work with a reputable supplier so that you will get more advice on how to properly maintain your CRPA simulator and the number of times that you have to do it on a yearly basis.

Have you ever wondered how some people can pass payment terminals or leave a store without paying? Thanks to new technology, payment is simply a few taps on their smartphones. Such is happening at the present because of Near Field Communication or NFC.

Before purchasing NFC tags for your business, you must first understand how it works. NFC provides wireless technology that allows users to pay by placing either a card or their smartphones within a few centimetres on a device like a terminal or another smartphone. It transmits data using electromagnetic radio fields.

Most people are only familiar with Radio Frequency Identification (RFID). It works the same way and uses the same mechanism but only within a very close range. NFC, however, provides many benefits with its contactless transactions, according to NFC Direct. For these reasons, many business owners consider investing in this technology.

Social Media Marketing

Stores that use NFC technology may utilize it further on social media platforms like Facebook. By reaching out on social media, you attract more people to your store, and the NFC tech can provide fast and easy discounts or special promotions that can motivate them to visit your store. Doing so is an effective but subtle marketing strategy.

Direct Connection with Customers

With one scan, customers can know more about the products they want to purchase. It is convenient for you, as it gives your shop the ease of having to explain all the products manually, and for the customer, who will have the information they need right at their fingertips.

Growing Trend

If you do not have it, chances are, your competitors do. If they can maximize NFC technology’s benefits and provide a more convenient experience for customers, you could be missing out. Investing in the technology levels the playing field and provides your customers with the same high-tech experience.

Utilizing NFC technology is a growing trend that is here to stay. The world continues to advance, and your business should be able to keep up. Invest in NFC technology and see how your business can benefit from the convenience it brings you and your customers.

Most people today will get along with a very basic global positioning system (GPS) app on their smartphones. That’s especially true when all you need it for is to travel within your city or short jaunts to the countryside.

If you’re a more serious adventurer, want to go transnational with your business, or even simply enjoy longer and further drives, then you need a dedicated GPS unit with features such as CRPA simulation. Here are the three benefits of getting one for yourself.


The biggest benefit of dedicated units is that they’re built to be far stronger. Shock- and drop-proofing are very basic features. These make it resistant to the wear and tear caused by constant use and even the toughness of the terrain that you might get into.

They’re also weather- and waterproof, which makes them perfect for travel over terrains where the climate varies a lot. Knowing that it will function in the most extreme situations makes these types of units a worthwhile investment right off the bat.


GPS apps on our smartphones rely on line of sight with cellular towers to function with any degree of accuracy. That’s why those apps can be adversely affected by bad weather, rough terrain and even signal interruptions.

With a dedicated unit, you rely on four satellites unencumbered by the same problems. This is something you can even test with built-in CRPA simulation. This arrangement makes it far more accurate and reliable.


The maps built into dedicated GPS units are a cut above those you will find on your smartphones. Apart from the specificity of locations, these maps also include information that provides altitude date and often integrate real-world weather patterns.

This setup ensures you have all you need to plan your trips whether for business or pleasure more carefully. This is perfect for those who take their adventures more seriously.

If you need these all in a GPS device, then you should definitely get a dedicated unit for yourself.

Apps have become popular along with smartphones, which is why many businesses today take the time to develop a mobile app to appeal to their clients.

Here are some tips if you want to launch your own app:

Have it Done by Professionals

There is nothing like hiring the right people to provide you with professional mobile application development services. This is usually better than trying to create the app in-house. The App Team notes that with professionals handling the job, you can pay them on a per-project basis while you keep running your business.

Build and Launch It Right

It also helps to have a powerful social media presence even before the launch. Give your customers an idea about the release of your app several months in advance so that they will anticipate it when it finally hits the stores. To do this, you will have to bank on your current social media standing. If you do not have one yet, it’s time to build one.

Prepare Your Help Desk

All apps have might have an issue no matter how many tests you have. Make sure you have a team to man the Help-line a few days after the app goes live.

Offer Promo Codes

Provide promo codes for app purchases a few days before the launch. Incentives can be given, depending on the type of business you have. For example, buyers through your app can enjoy discounts or free delivery. A point system may be available for use in the future. You can provide updates through the app that will benefit users.

Partner Up

Partner your app with other developers or other users who match up with what you provide. You can also try partnering with social media influencers to review the app or feature it in one of their segments.

Of course, these are just some of the things to keep in mind when launching your own mobile app. Remember that it pays to check the competition so you know what features are appreciated and which ones need to be added.

Automakers and technology firms will test self-driving cars on California’s roads aside from mechanical testing labs by early April, following approval was given to the state Department of Motor Vehicles (DMV).

The permit allows the DMV to publish ground rules for companies that plan to use streets as their testing ground for automated vehicles. So far, the state has issued permits to 50 companies that intend to test driverless cars.

Safety Rules

One thing that makes this progress on self-driving vehicles is the elimination of a rule, which will allow automated cars to be on the streets even without a person inside in case of an emergency. The DMV removed this from their set of ground rules effective on April 2.

Despite this, DMV Director Jean Shiomoto said that they would only work with companies that are ready to conduct testing on 100% driverless vehicles. Uber, which has been testing its version of self-driving technology, urged California to consider permitting tests for autonomous trucks as well. However, some groups are already concerned about the idea of letting fully driverless cars roam the streets.

Compliance and Cooperation

While there is some concern over the state DMV’s action, not all companies may just proceed to test automated technology. Car companies must be able to convince state and federal authorities that their vehicles are compliant with safety regulations, aside from being compliant with traffic laws.

Otherwise, the state DMV will not issue permits to them. Another requirement involves cooperation with local officials where developers plan to test vehicles. Some cities such as Sacramento have invited some companies to do their testing around the state Capitol.


Driverless cars are a sign of future transportation not only in California but also in the U.S. What do you think of sharing roads with cars that have no people behind the wheel?
