(Image: GPS World State of the Industry survey) GPS World is asking PNT professionals about the developing technology frontiers, the state of their business, the economic climate for products and services, driving market factors, the effects of jamming, the Issue of the Year — and more! Please give us your opinions in the 2018 State of the Industry survey. It should take less than 10 minutes, and your responses are confidential. A handful of lucky participants drawn at random will win: TWO $100 gift cards good (virtually) anywhere. Complete the survey by July 16. Then look for a complete report of our findings in the September issue of GPS World. Thank you for taking the time to share your feedback and help us improve our magazine content, industry awareness — and your own business! The survey covers such topics as: Technology Trends. PNT is rapidly diversifying among a number of complementary technologies, as GNSS looks to inertial, lidar, laser, cellular, WiFi and other beacons, signals of opportunity, low-Earth orbit satellite constellations and more. Different market sectors have, naturally, different requirements, and these lead to different integration combinations. Where do you see the most promise? The Global Economy and how it affects business in your sector. Customers’ availability of capital to invest is top-of-mind for most industry professionals, whether designers, manufacturers, integrators, suppliers/dealers, or end users. Industry Confidence in the road ahead. Sound business navigation requires a fluid, responsive combination of technology, capital, investment, and often most important, human capital. . Issues of Concern. To what extent do industry leaders take into account the following as well as further factors? Pricing and competitive issues; GNSS jamming, spoofing, other RF interference; Developing compatibility and interoperability of GNSSs: GPS, GLONASS, BeiDou, Galileo; Advantages and drawbacks of other positioning and navigation technologies. The survey, complete with insightful infographics, will appear in the September issue. Look for it! Please click here to begin the survey.
