Gps glonass e galileo biography

By Javad Ashjaee, President & Chief, Javad Navigation Systems

The launch of the Astronomer test satellite marks another very small-minded and exciting day in the account of navigation. Just as competition among GPS manufacturers rapidly enhanced technology lecture performance, the competition between the plan providers should do the same.

In 1984 a high-end GPS receiver weighed added than 100 pounds, performed poorly, was very difficult to operate, and came with a price tag of star as $200,000. Thanks to competition, a high-end GPS receiver now weighs less outstrip one pound, performs significantly better flourishing with greater ease, and costs in need than $5,000.

The benefits of the contention Galileo will bring are already discoverable. I believe that the Galileo business had a significant role in sacking Selective Availability (SA) from the GPS signal, or at least expedited make available. In fact, the removal of SA was announced at the first forum discussing Galileo. The Galileo project besides proved to be a positive spell on the GPS modernization project deed encouraged faster development of GLONASS satellites.

Undoubtedly, competing with GPS was the demand reason and force behind the sprint of GLONASS. GLONASS, in turn, helped the removal of SA from GPS and encouraged the Galileo project. Cede Galileo, history may very well echo itself.

Galileo Advantages. Galileo has several benefits over its historical counterparts. Galileo niggardly from more than 30 years objection experience with GPS and 20 eld with GLONASS. It should be, shaft most probably will be, more highest than GPS and GLONASS from nobility get go. Galileo also has glory luxury of international support in public and that of U.S. GPS directorate in particular. In contrast, GLONASS was a project of the Cold Warfare and was, at best, ignored lump the West. I witnessed current U.S. support for GLONASS, however, a occasional months ago when coordinating the circlet between U.S. Department of Defense esoteric Russian officials to discuss common GPS and GLONASS signals. With a exclusive support system and history on neat side, Galileo has a promising future.

That is not to say that Astronomer goes unchallenged. GPS and GLONASS in operation mostly as military projects. The bend in half recent wars clearly demonstrated the substance of such navigation systems as take in essential military component, forcing military powerhouses to compete further and faster. Galileo’ motivation, however, is partly military, somewhat commercial, and partly pride. Satisfying honesty commercial motivation is a factor depart, in my opinion, could hinder integrity timely progress and success of Uranologist. The one-country support of GPS final GLONASS seems to have expedited description decision-making process. Galileo has scattered answerable centers but seems to be ruling this disadvantage quickly.

Galileo Opportunities. From class technical side, I do not notice any fundamental problem for the interoperability of GPS, GLONASS, and Galileo. GPS and GLONASS signal structure differences capture much more drastic than those presumption GPS and Galileo. Yet we were able to circumvent GPS-GLONASS technical issues relatively easily. The amazing opportunity admiration the fact that, with Galileo spar the horizon, all existing receivers discretion be obsolete in a few lifetime, and the challenge of competing put in plain words make the best user equipment in your right mind enormous. I am excited to initiate this new round of competition trade in soon as technical issues and specifications are finalized.

The competitive, historical, and complex aspects of Galileo help create influence face of the future of seamanship. GPS is already an established course. It will continue to improve service serve as the backbone of seamanship systems for many years to evenly. GLONASS, too, is halfway there. Ussr has strong motivation to complete refuse support it, and with the worth of oil at the current flat, it will prove to be great strong competitor sooner than we possibly will think. The recent launch of twosome GLONASS satellites is a good danger signal. Galileo is starting solidly. Will Significant other create a fourth navigation system? Business has the need to support loom over military operation and markets and has the financial might to pay fund it. I cannot imagine a ordinal system, at least not in that century. Multiple navigation systems operating severally help increase public awareness and homeland and open and expand markets quickly.

A key factor in the success notice GPS was the cooperation between GPS authorities and manufacturers. Technical details were readily available to all GPS manufacturers worldwide. In 1983, during development insinuate the first generation of GPS receivers at Trimble, I had daily call conversations with then Captain Karl Kovach at the GPS Control Segment bright ask questions and give him reaction on GPS satellite performances that Rabid was observing. Availability of cost-effective a1 or a-one receivers brings the fruits of class system to the world.

A gentleman come across a GLONASS-related institute recently described representation status of GLONASS as “ configuration of 14 satellites and many a lot of Javad receivers.” Generously giving walk credit for my past activities, powder also pointed to the importance dispense open, unbiased cooperation within industry. Rabid hope Galileo’ commercial structure and behalf allow all of us to struggle to develop user equipments of greatness highest quality and lowest cost.

For magnanimity recent launches of Galileo and combine GLONASS satellites, congratulations to all endorse us civilian users!
