I am used to working with Trimble. But I wonder if a TOPCON HIPERLITE BASE AND ROVER CAN BE USED AS JUST 2 RECEIVERS to collect rapid static or static data to be submitted to OPUS for a solution?
Thanks for your help
Dane,
As long as both receivers have the memory option activated then they can collect static data which can then be submitted to opus.

If the height component of your solutions is critical, you ought to test the Hiperlites against some standard antenna. It seems to me that I recall finding that the Topcon antenna models OPUS uses were screwy and gave a consistently biased answer that was wrong by about a couple of tenths of a foot. Since I don't use Hiperlites, I never followed up on that to learn exactly where the problem lay.
THANKS DYLAN,
THANKS KENT
My primary concern is not vertical.
I keep eyeing EBAY for recievers.... trimble. I could have bought a pair of 4800's with extras for 5K....

That was a great deal -- I was tempted, but really have little use for RTK.
If static and rapid-static is your real interest, there's a Trimble 4400 system on eBay with a Buy It Now price of $1,900.00. It's been up for auction before, so an offer of $1,500.00 might be enough.
Using a 4400 is a little inconvenient because you have to store the data on the TSC1 that's included in the sale, but aside from that it looks like the only things you need to add to the system are a battery and charger. (You might need a PCMCIA card reader to get the data off the card; I can't tell if a download cable is included.)
The system is listed as "As-Is" because the seller doesn't know how to test it, but it reportedly came from Iowa DOT, so it's probably in operational shape.
Jim, thanks for the link… it was definitely “déjà vu all over again”.
He’s got some Ashtech/Sokkia L1/L2 gear as well. Some of the stuff (junk) would only fetch the price he’s asking for a Hollywood movie prop and others are just plain WAG’s... $80 for an old Sharp fax plus $20 S & H … when you can buy a new all in one for $120!
Dane,
As Dylan mentioned, it depends on the model of Hiper's that you have. I ran Hiper XT's for many years and loved them for both rapid static and RTK. I have the GRS-3's now and those work similar. Some Hiper models don't have the built-in RAM to store the data files with static.

Severe Thread Highjack!! I know there have been threats to shut down the CA BPELS. What do you think about all this hubub in Florida, Texas and Rhode Island? Or can you discuss that sort of thing? I can't imagine the CA legislature just putting a big X through the PLSA, but these are strange times.
Ric
I am asking for a friend and all I was told is they they are Hyper lite pluses. and that is all I have for a model number. So I'll check and see if memory can be added to thee units.
thanks for you help

It all boils down to “a government big enough to give you what you want is strong enough to take away what you have”… I think California Governor Reagan is credited for this statement
Ric
I am not aware of any threats to the California Board for engineerings, land surveyors and geologists. We are currently involved with the Sunset process which all boards in California are required to address on a regular basis. Consumer Affairs's hearing was Monday and ours (along with Contractors, Architect's, etc.) are scheduled for next Monday. There doesn't appear to be anything that we were not expecting on the agenda at this time.
As for the Texas, Rhode Island and Florida situations, while I do not have any first hand knowledge or specifics, I would say that it is fallout from state budgetary issues more than anyone specifically targeting land surveyors. My guess is that Texas may consolidate with the Engineers board. Florida seems way too up in the air from what I read.
The Rhode Island situation that I have read (just like you) appears very interesting as it seems to target specifics about technical standards in regards to what civil engineers can do. We do not have Minimum Technical Standards stated in our laws which I very much like. The California legislature has seen fit over the years to recognize the professionalism associated with the engineering and land surveying practices rather than focus on the technical aspects of our respective practices. I believe by having minimum technical standards in statute or regulation, the perception of those professions are more of a technician level rather than a professional level.
Consolidating boards may or may not be a good thing. Eliminating can have an entirely different effect. As you probably know, the former Geology board was consolidated into our board about a year and a half ago. And I believe this has turned into a good thing for the geologists. Better to be one of several ducks in a pond, than a big duck in a dry pond.
While I can understand why things are even being considered from a budget perspective, I fail to see how eliminating a regulated practice such as land surveying is beneficial to the general public. As one of my first mentors told me a long time ago, outside of blood relatives and money, land is a person's most prized possession.

Actually it was Ford
I do not think ANYONE IS ASKING the government for anything. The people TELL their representatives what they WANT the role of government to be and then representatives busily set about pleasing the corporate paymaster.
Ric
I believe Hiper Lite Pluses were capable of storing static data files.
Edit: I've sat with a technician looking at the inside of Hipers several times. If it is capable of memory, it is basically an SD card slot only accessed internally. The cost to add is generally much more than you would think just by seeing the costs of those cards
Ric
Thanks for the reply, Ric. Maybe I have viewed the sunset clause too seriously in the past. I have noticed a major cutback in services from the California Board due to budget constraints in the past few years, though, and with the current climate of cut and slash, I just wondered if there were rumblings of more serious consequences to come.
By the way, I completely agree that Minimum Technical Standards, such as mathematically defining "material discrepancy" would be a very bad idea.
Ric
The budget issues are very much affecting our operations as it is the majority of the boards under DCA. It's just becoming more and more difficult for the Board to absorb the cuts and shielding the impact from the licensees, applicants and public.
While we are special funded (primarily by renewal fees), this doesn't protect us from the general fund woes that everyone hears about.
The answer is yes if they have memory but many were sold without memory as RTK only units. You can use the free PCCDU to see if the units have memory and how much plus you will want to change the default 1 second rate to 15 or 30 seconds. No reason to just have data to through away unless you plan to 'roll' your own processing.
The antenna problem had nothing to do with the Hiper series of units. It was with another external antenna.

Actually, you don't need memory to do this.
The catch is, you can only do it one day every two weeks. Cinderella Tuesday.
You can create an OPUS file using PC-CDU and save it to your field computer. I've done this a few times, it works good.
So, if you don't need to do this all the time, this might be the way to go.
This Tuesday (the 22nd) is the next Cinderella day.
:coffee:
BTW, All Hiper receivers have memory installed in them. You just need to buy the OAF file to activate the memory. Last I checked it was $500 for 4meg.

STATIC ROVER AND BASE:
I have those receivers, and I do that exact thing all the time. I find it hard to believe that they would have been sold without the ability to record static observations. What does it matter if you have it set to a Rover or Base? You just record the data, and then use your post processing program to sort it out.
When using static, there is no setting on the machine to make one a base or one a rover. Each is just recording the raw data that it receives into a certain format of file. You determine base and rover in post-processing...
MEMORY:
If they do not have the memory enabled, and you don't want to pay for it, SurvCE says it has an option to record static to my data collector, but I have never used it. (Check with Carlson...)
PC-CDU:
You can set the recording rate for static processing, also you can review the features that are enabled/purchased for these receivers. Also you can enable/disable the Cinderella feature that was discussed earlier. (I have no idea why someone would turn it off...but it is sometimes.)
Also, with those units, you set each to be either a Rover or a Base when using RTK. You can do this yourself, with PC-CDU.
PC-CDU is a program from Topcon, which you can download from their site.

TOPCON QUESTION - Answer: "Yes"
I used PC-CDU for about 3.5 years. I was just told a few months ago that the new Topcon Utility TRU is the best utility to use to download the receivers. This came directly from a Topcon Dealer, and They have always steered me in the right direction.
