    My friend asked me what would be my first impressions on those big
    GNSS Rx brands serving the Survey industry. I have to admit this
    question is really beyond my wits. Anyway I decide to answer as much
    as I could, and hopefully there are some "insiders" that can give us a
    better answer. I suspect most of my answers are either out of date or
    quite inaccurate. If you would like to help, please contribute to the
    list.

    1. Trimble
    Pros: It might be the biggest player in the market, and designed te
    first GPS receiver for the civic. I felt its hardware design is very
    strong, R&D is good.
    Cons: I don't know.

    2. Topcon/Sokkia
    Pros: It is among the top 3 biggest payers. Its marketing and sales
    support are not bad.
    Cons: Its R&D team is instable after Javad left.

    3. Leica Geosystems
    Pros: It is among the top 3 biggest payers. Its marketing and sales
    support are not bad.
    Cons: Its receivers are based on NovAtel's OEMs. They don't own the
    core techologies.

    4. Javad
    Pros: The performance of their high-ends is amazing.
    Cons: Their marketing share is not proportional to their tech.

    5. NovAtel
    Pros: Their OEMs have stable performance, possibly due to the anenna,
    RF circuit and tracking loops.
    Cons: Their R&D is weak, and produces no new techologies for years.
    They buy technologies from outside.

    6. Septentrio
    Pros: Their R&D is relatively strong and the response to new
    technologies is quick.
    Cons: Rumors said lots of office politics there.


    7. Ashtech is coming back.
    Pros: good reputations in 80s and 90s.
    Cons: has left for too long. Not sure if it can catch up.
