LX Navigation Introduces the New LX 9090 Zeus
The LX 9090 Zeus features a 5.5 inch colour screen and runs a new LX
Navigation glide and nav software. It has the ability to show either a 2D or 3D terrain moving map on screen. For more details visit the LX Navigation section at http://www.foxonecorp.com or http://www.lxnavigation.si/avionics Delivery of the new Zeus are scheduled for the end of May 2012. |

The screen shots look very much like the LX9000 software (by LXNav), however LX Navigation claims to have developed the software "completely". This is confusing. And the LXNav vs. LX Navigation story is already confusing enough. Max |

LX9090 uses Linux Hello Guys! Sorry my bad english! As I heard complete story: First was LX Navigation company and they developed all instuments Colibri lx16, lx166,lx7000, lx7007 itc.. and also lx8000. Then some developers left the company and start new bussines with LXNav company. Mr. Rojnik gave them rights to sell LX8000 product + also the get market, NAME and dealers. At first they were working friendly companies, but if you sell similar products it can cause that happened here. They become biggest competitors. LXNAV Product: - Nano runs on microcontroler - LX8000,LX9000, LX8080 run on Linux Lx Navigation products do not run mostly on Windows OS. This is not true. Colibri2, Lx7007 color run on microcontroler. And Zeus on linux. Only Minimap runs on Windows, because it is PNA device. They adjusted LK8000 from Paolo Ventafridda to work with some buttons,button color, and communicate with internal microcontroler. This customization is very small, generally is completly normal LK8000. This is some cheap option to have good instrument visible on sun for low cost. I saw this device in air and it is good. It is nice cooperation of Paolo as software and LX navigation for hardware. If you want you tcan run also other PNA program like SeeYou, Xcsoar. |

I sent a few questions about the LX 9090 Zeus to LX Navigation, in an attempt to resolve my confusion, here are the answers from Crtomir Rojnik: Q: Is this a team effort by LXNav and LX Navigation, or did you adapt LK8000 to look like the LX9000, or did you really write a new software from scratch? A: "LX Zeus is using LX Navigation original SW, there is no adaptation of LK at all."; "Yes, we did new SW for LX Zeus." Q: Are customers free to replace your new software with a custom one on the hardware they own? A: "at the moment we don't plane Zeus running under SW like XCsoar. MM family will continue on free ware SW." Q: Does it run Linux or Windows? A: no answer, question was ignored. Q: I heard the LX Zeus runs Linux, is that correct? A: no answer, question was ignored. Q: The MiniMap and the LX8000/9000 are all based on the old ARMv5 architecture. Did you choose a modern CPU architecture for the Zeus? (i.e. ARMv7 with NEON and OpenGL) A: no answer, question was ignored. Unfortunately, nothing new. All interesting technical questions were ignored, not even the choice of operating system is disclosed at this point. Can't wait to analyze the firmware image when it's out, to see if the software was really developed from scratch. I don't think there's a market for yet another commercial gliding software - writing one costs millions, but the market is too small. I don't think any company can afford to write a new one from scratch, it'll never pay off. It would need to be a "killer" app that everybody wants to buy. The new 3D terrain display is not even something I find even remotely useful. Max |

LX Navigation Introduces the New LX 9090 Zeus
Dear Max et all,
I am the lead developer of the Lx Zeus product. My colleagues have informed me that some misleading/wrong is being shared on various glider forums. Just to clear things out, I would like to point out a few things: * Zeus is a multiprocessor platform. The main processor is a high performance RISC Cortex A8 - 750 MHz (1GH comes soon). OpenGL is also used for graphics rendering (essential for 3D). At least two more high performance ARM7 micro- controllers are essential for correct operation. One takes care for the peripheral interaction, especially for the CAN - 485 interaction, while the other is used for inertial (AHRS /vario) calculation. It depends on the Zeus version. More uCs can be added later via CAN bus connection. * Zeus runs Linux. Pure, vanilla Linux was taken and then heavily patched in order to get it running. Some in-house developed drivers were necessary to get the openGL running and the CAN messages into Zeus. * Zeus is pure CAN system. Can bus is the main bus. It is loosely based on the CANAerospace formulation, which was significantly extended to cover additional needs. Complete 485 bus (old LX bus) is also fully supported and one of the uC roles is to take care for the communication between both buses. * The software in Zeus was written from scratch. It is completely in- house developed. It is coded in C++. Significant portions of the mathematical model logic is written in pure C++, which is not platform dependent. This means that a significant portion of code is the same in 7007C and Zeus. Please note that 7007C code was also written from scratch and not a single line of code from old 7007 was used. * The graphical interface in Zeus is build around Qt library. In 7007C, we developed own library. * Although I am familiar with the XC soar and LK, not even a line of code was used from there. The programming approach, abstraction and platform differences were simply too large for this to be effective. * Zeus as such is pretty a complex product and it is difficult to handle on OS level. It requires special patches and drivers. For this reason, I find it difficult (but not impossible) to be a host for LK or XC soar systems. We definitely do not have enough man power to dig into this. * You will notice firm Kanardia d.o.o. to which I belong. Mr. Rojnik (head of LxNavigation) is my lifetime friend and after the issues with the lxnav, we are working together with Lx Navigation on development of new products. Most of technology used in Zeus was developed and tested by Kanardia in previous years. Note: Almost identical email was sent to Max. With very best regards, Aleš -- Dr. Ing. Aleš Krajnc Kanardia d.o.o. Ulica heroja Rojška 70 SI-3000 Celje Slovenia Mob: +386 40 360 512 Tel: +386 590 12 521 Fax: +386 590 11 416 URL: www.kanardia.eu |

I sent a few questions about the LX 9090 Zeus to LX Navigation, in an attempt to resolve my confusion, here are the answers from Crtomir Rojnik: Just in case anybody else is interested in the technical details, I've got an informative email from Ales Krajnc, who was involved in the design of the LX 9090 Zeus. Q: Does it run Linux or Windows? A: no answer, question was ignored. The LX Zeus indeed runs Linux. It is a custom Linux distribution, and the application is based on Qt. The firmware image from a similar product by the same company (Kanardia Nesis, http://www.kanardia.eu/products/nesis) suggest that the LX Zeus runs a Debian-like distribution, Linux kernel 2.6.24, Qt 4.6.2. Qt runs on top of the frame buffer. Q: The MiniMap and the LX8000/9000 are all based on the old ARMv5 architecture. Did you choose a modern CPU architecture for the Zeus? (i.e. ARMv7 with NEON and OpenGL) According to Ales, the LX Zeus has an ARMv5 CPU with 750 MHz (the firmware has XScale drivers). That leaves me unimpressed, because this is only slightly better than the ancient hx4700 (ARMv5 620 MHz). Contemporary mobile phones have dual-core ARMv7 CPUs with 1200 MHz or more. Max |

Strange thinking Max!
I do not know why you compare procesor in Zeus with new procesors in Mobile Phones. I believe that they wont run android + hundreds of application on this device. If you have written application for specific hardware it does not matter what processor is inside, if peformance is good. So if they run 3D on 750MHz processor and works good, I would say that they are good programers. Also on 1200Mhz dual core you can have non optimized code and can run slow. I say that we wait until is out and see what its performance! I do not know where your problem is Max...? |
