L1L2 vs L1L5: Which dual-band GNSS RTK receiver is better today?
Вставка
- Опубліковано 13 лис 2023
- Have a closer look at dual-band RTK GPS receivers. We're comparing two types - L1/L2 and L1/L5 - to see which one is better nowadays.
If you're interested in GNSS and want to know more about these receivers, we tell you what's true and what's not!
🌟 What We Cover:
0:40 Myth-Busting: With a lot of information floating around, we separate fact from fiction about these receivers' cost-effectiveness and performance.
1:05 Is L1+L5 cheaper than L1+L2? Delve into the specifics of receivers, discussing their history, pricing, and more.
1:53 Does L1+L5 perform better than L1+L2? Learn about the frequency ranges, satellite availability etc that affect on the performance.
2:54 Is it time to switch to L1+L5 since it is newer technology? Let’s consider infrastructure. Most of the world's functioning RTK Base stations are currently L1L2. Are they compatible with newer L1L5 rovers?

How do I figure out If I have more (or if any) L2 or L5 base stations in my area?
Not a straightforward task...
- If you have a preferred service provider, simply ask them for this information.
- If you are looking for service provider, you can use this database to check the options in your country. First look for a base station near you, and then enter in the specification sheet of that base station. It is usually mentioned there: www.ardusimple.com/rtk-correction-services-in-your-country/
2:14 Is there a reference to " many satellites supporting the L5 frequency have encountered technical challenges remaining inactive or unhealthy years after launch. As a result fewer L5 satellites are currently fully operational compared to L2"? Any reference links would be appreciated.
Latest updates can be found at an official webpage of the US government www.gps.gov/systems/gps/modernization/civilsignals/ if you go to the section of "L5", you will find "Pre-operational signal with message set "unhealthy" until sufficient monitoring capability established" and "However, L5 remains pre-operational and should be employed at the user's own risk until it is declared operational."
@@ardusimple Aha... US Government Data..... Would not trust that as most L1+L5 hardware are manufactured in Asia. hence they will try and protect their market segment with L1+L2 manufacturers
The claim that L1 L5 is not cheaper than L1 L2 is not true. The end user is not interested in the cost of production, but in the purchase price at which it can be bought. And in the shops, L1 L5 devices are cheaper. And L5 corrections are now available almost everywhere. This video is misleading.
The price comparison is only a small part of the 5min video.
Prices change over time and tend to go down, when the video was released all the reliable units we tested had same price for L1+L2 and L1+L5. Notice that we are talking about RTK enabled GNSS receivers.
L1+L5 non-RTK receivers are cheaper, but so are L1+L2 non-RTK receivers.
@@ardusimple the price comparison may be only a small part of the video, but it is an essential part and misleading! I am also talking about RTK-enabled GNSS receivers.
L1+L5 RTK receivers are clearly cheaper than L1+L2 RTK receivers. Let me not make examples of competing products now...
Fully agree above comment, it's almost nonsense, you have never mentioned that L2 signal will be influenced by 2.4G band 400MHZ radio rather than L5, even now in some countries they made man-made interference, the most influenced frequency is still L2.
In addition, when you mention that currently most of the CORS is L1, L2, I thought that you even dont know current situation, or you deliberately misleading the audience.
Thank you for your comment, you make very good points that we will be happy to discuss:
- GPS L5 satellites today are still broadcasting with the healthy flag OFF: any receiver outputting raw data can confirm this. For this reason many vendors even if they have L5 in the specification sheet, today their default configuration is still with L5 disabled.
- CORS networks. "Premium" CORS networks are indeed L1/L2/L5, but low cost (which are the ones attractive for low cost users) are still highly populated with L1/L2 receivers. Some countries have the luxury of having free L1/L2/L5 CORS networks, but this is not the case in the majority of countries and majority of installed base stations. After the launch of ZED-F9P 5 years ago, the number of L1/L2 base stations installed globally has boomed.
- Interference immunity. Unfortunately in a 3 minute video it is not possible to go into all details, we only try to provide a general guideline. If you want interference immunity, go for an L1/L2/L5 receiver. Trying to guess if L2 or L5 will be less jammed it's just betting. GPS signal arrives to the ground around -130dBm (for the non techies this is dividing by 10000000000000 compared to a WiFi transmitter). Anything jamming L2 can potentially also jam L5.
🤣🤣🤣🤣🤣It's nonsense. Are you afraid of the market?
Thank you for your comment. Note that the video is regarding low cost RTK receivers and not related to standard GPS tracking. Actually we have both L1/L2 and L1/L5 receivers in our portfolio and we are happy to sell both. But today the number of customers having a bad first experience with L1/L5 receivers in increasing, and we are just trying to make their life easier based on our own data.
